| 1 | |
| 00:00:20,670 --> 00:00:24,930 | |
| بسم الله الرحمن الرحيم المرة الأولى اتخذنا كيف | |
| 2 | |
| 00:00:24,930 --> 00:00:30,790 | |
| نحسب ال variance و ال standard deviation القانون و | |
| 3 | |
| 00:00:30,790 --> 00:00:33,630 | |
| طلبنا منكم انه في ال .. في البيت تحاولوا تعيدوا | |
| 4 | |
| 00:00:33,630 --> 00:00:40,910 | |
| للحل فى حد عاد الحل و طلع عنده إجابات غلط يا بات | |
| 5 | |
| 00:00:40,910 --> 00:00:44,970 | |
| فى حد رجع البيت و عاد الحل و طلع عنده مش نفس | |
| 6 | |
| 00:00:44,970 --> 00:00:49,130 | |
| الإجابة اللى موجودة هنا لأنه فى الامتحان هجيكم | |
| 7 | |
| 00:00:49,130 --> 00:00:57,060 | |
| مثال مشابه لهOkay اليوم هنحكي في موضوع مهم ال how | |
| 8 | |
| 00:00:57,060 --> 00:01:02,900 | |
| we can calculate the rate of return كيف ممكن نحسب | |
| 9 | |
| 00:01:02,900 --> 00:01:06,680 | |
| ال rate of return حكينا الطرق السابقة كنا نعتمد | |
| 10 | |
| 00:01:06,680 --> 00:01:09,640 | |
| على طريقة اسمها ال arithmetic method طريقة الاش | |
| 11 | |
| 00:01:09,640 --> 00:01:14,360 | |
| arithmetic طريقة ال arithmetic هي طريقة الحسابية | |
| 12 | |
| 00:01:14,360 --> 00:01:18,660 | |
| بيسموها في طريقة أخرى بيسموها geometric method | |
| 13 | |
| 00:01:19,290 --> 00:01:22,770 | |
| geometric methods اللي هو الطريقة الهندسية okay | |
| 14 | |
| 00:01:22,770 --> 00:01:26,790 | |
| إذا إحنا في أمام two different methods in | |
| 15 | |
| 00:01:26,790 --> 00:01:30,670 | |
| calculating the rate of return يعني في طريقتين في | |
| 16 | |
| 00:01:30,670 --> 00:01:34,790 | |
| احتساب ال rate of return طريقة ال arithmetic | |
| 17 | |
| 00:01:34,790 --> 00:01:41,710 | |
| وطريقة ال geometric okay طريقة ال arithmetic هي | |
| 18 | |
| 00:01:41,710 --> 00:01:47,420 | |
| طريقةيعني أغلب الناس بيستخدموها لو إحنا أعطينا | |
| 19 | |
| 00:01:47,420 --> 00:01:53,180 | |
| مثال for instance أخدنا | |
| 20 | |
| 00:01:53,180 --> 00:02:02,340 | |
| مثال بقولنا calculate the average rate of return | |
| 21 | |
| 00:02:02,340 --> 00:02:11,120 | |
| في | |
| 22 | |
| 00:02:11,120 --> 00:02:17,790 | |
| ال past yearكان 9% في ال second year 10% في ال | |
| 23 | |
| 00:02:17,790 --> 00:02:30,330 | |
| third year 12% 8% and 5% احنا اجتنح البيانات هذه و | |
| 24 | |
| 00:02:30,330 --> 00:02:33,710 | |
| بنحسب ال average rate of 10 مين بعرف يحسب ال | |
| 25 | |
| 00:02:33,710 --> 00:02:38,950 | |
| average rate of 10 متوسط متوسط العائد مجموعة مع | |
| 26 | |
| 00:02:38,950 --> 00:02:48,400 | |
| العددهم يعني بنقول مثلا5% بيقول 9 plus 10 plus 12 | |
| 27 | |
| 00:02:48,400 --> 00:02:57,340 | |
| plus 8 plus 5 على 1,2,3,4,5 كام | |
| 28 | |
| 00:02:57,340 --> 00:03:00,460 | |
| بيطلع؟ هاي الألات الحاسبة معاكم أربعة و أربعين و | |
| 29 | |
| 00:03:00,460 --> 00:03:03,960 | |
| أربعين و أربعين و أربعين و أربعين و أربعين و | |
| 30 | |
| 00:03:03,960 --> 00:03:04,620 | |
| أربعين و أربعين و أربعين و أربعين و أربعين و | |
| 31 | |
| 00:03:04,620 --> 00:03:05,020 | |
| أربعين و أربعين و أربعين و أربعين و أربعين و | |
| 32 | |
| 00:03:05,020 --> 00:03:06,880 | |
| أربعين و أربعين و أربعين و أربعين و أربعين و | |
| 33 | |
| 00:03:06,880 --> 00:03:07,460 | |
| أربعين و أربعين و أربعين و أربعين و أربعين و | |
| 34 | |
| 00:03:07,460 --> 00:03:09,040 | |
| أربعين و أربعين و أربعين و أربعين و أربعين و | |
| 35 | |
| 00:03:09,040 --> 00:03:10,980 | |
| أربعين و أربعين و أربعين و أربعين و أرب | |
| 36 | |
| 00:03:14,360 --> 00:03:22,220 | |
| 8.8 8.8 طيب 8.8 طيب ايش احنا سوينا عمليا احنا we | |
| 37 | |
| 00:03:22,220 --> 00:03:25,180 | |
| use the arithmetic method استخدمنا ال arithmetic | |
| 38 | |
| 00:03:25,180 --> 00:03:30,440 | |
| method طريقة الحسابية قلنا اللي the summation of R | |
| 39 | |
| 00:03:30,440 --> 00:03:36,180 | |
| divided by N okay | |
| 40 | |
| 00:03:36,180 --> 00:03:41,190 | |
| يعني جمعنا ال R و قسمناها على Nهذه الطريقة اللي | |
| 41 | |
| 00:03:41,190 --> 00:03:46,610 | |
| احنا استخدمناها في ال .. طيب في طريقة تانية ممكن | |
| 42 | |
| 00:03:46,610 --> 00:03:50,690 | |
| احنا نستخدمها؟ طريقة الهندسية، طريقة الهندسية، في | |
| 43 | |
| 00:03:50,690 --> 00:03:58,330 | |
| حد سمعت عن الطريقة الهندسية؟ كيف؟ طريقة الهندسية | |
| 44 | |
| 00:03:58,330 --> 00:04:02,910 | |
| يعني مشابهة للمتتاريات طيب خلينا عشان نفهم الطريقة | |
| 45 | |
| 00:04:02,910 --> 00:04:09,620 | |
| الهندسية ناخد بفعل بسيططبعا حطوا فى رأسكم ان هذه | |
| 46 | |
| 00:04:09,620 --> 00:04:12,140 | |
| this is arithmetic method هى طريقة ال arithmetic | |
| 47 | |
| 00:04:12,140 --> 00:04:19,560 | |
| الحسابية let's consider this هو هذا هذا هو نفسه | |
| 48 | |
| 00:04:19,560 --> 00:04:25,420 | |
| هذا هو نفسه هذا بس انه احنا ال R of state divided | |
| 49 | |
| 00:04:25,420 --> 00:04:31,160 | |
| by N يعني هذه المجموعة تعرفى محاسبيا او رياضيا | |
| 50 | |
| 00:04:31,160 --> 00:04:38,740 | |
| اللى هو واحد على N مجموعة R هذه نفسهابياضيان نفس | |
| 51 | |
| 00:04:38,740 --> 00:04:47,040 | |
| الحاجة يعني يا بنات x على n is equal 1 على n times | |
| 52 | |
| 00:04:47,040 --> 00:04:55,080 | |
| x معروف بياضيان هذا خلينا | |
| 53 | |
| 00:04:55,080 --> 00:05:03,640 | |
| ناخد مثال عشان نشوف how we calculate return in | |
| 54 | |
| 00:05:03,640 --> 00:05:04,280 | |
| different ways | |
| 55 | |
| 00:05:10,010 --> 00:05:15,730 | |
| خلينا هان بالجانب هنا لو one of the investors | |
| 56 | |
| 00:05:15,730 --> 00:05:19,090 | |
| invest his money starting by one hundred dollar | |
| 57 | |
| 00:05:19,090 --> 00:05:22,890 | |
| يعني واحد من المستثمرين بدأ بمية دولار يعني | |
| 58 | |
| 00:05:22,890 --> 00:05:28,970 | |
| starting the money by one hundred dollar okay and | |
| 59 | |
| 00:05:28,970 --> 00:05:32,830 | |
| in the first year he lost fifty dollar and at the | |
| 60 | |
| 00:05:32,830 --> 00:05:36,970 | |
| end he make one hundred dollar هيبس السنة الأولى | |
| 61 | |
| 00:05:36,970 --> 00:05:41,190 | |
| صارت ثروة تبعت وخمسين دولاربنهاية السنة التانية | |
| 62 | |
| 00:05:41,190 --> 00:05:44,530 | |
| صارت الفروة تبعت مية دولار he started by one | |
| 63 | |
| 00:05:44,530 --> 00:05:47,870 | |
| hundred and then he end by one hundred what is the | |
| 64 | |
| 00:05:47,870 --> 00:05:53,470 | |
| return؟ كدهش العائد؟ يعني هو بدأ بمية و خلص بمية، | |
| 65 | |
| 00:05:53,470 --> 00:06:00,750 | |
| كدهش استفاد من هالشغل؟ خمسين خمسين؟ هو بدأ يعني في | |
| 66 | |
| 00:06:00,750 --> 00:06:03,990 | |
| .. بدأ معاه مية دولار و انتهى بمية دولار، اش ولا | |
| 67 | |
| 00:06:03,990 --> 00:06:08,490 | |
| اش؟ اش ولا اش يعني what it means ولا اش؟ zeroso | |
| 68 | |
| 00:06:08,490 --> 00:06:14,430 | |
| zero because P1 minus P naught على P naught لأن P1 | |
| 69 | |
| 00:06:14,430 --> 00:06:21,470 | |
| هي ال ending price فمية minus مية على مية so it's | |
| 70 | |
| 00:06:21,470 --> 00:06:25,130 | |
| equal to zero طيب | |
| 71 | |
| 00:06:25,130 --> 00:06:29,530 | |
| احنا عاملين ايش سوينا we consider the investment | |
| 72 | |
| 00:06:29,530 --> 00:06:33,750 | |
| as a one period time يعني اعتبرنا ال investment كل | |
| 73 | |
| 00:06:33,750 --> 00:06:35,610 | |
| فترة زمنية واحدة okay | |
| 74 | |
| 00:06:37,850 --> 00:06:41,310 | |
| now there is other options to calculate return | |
| 75 | |
| 00:06:41,310 --> 00:06:44,590 | |
| ممكن حد يفكر بطريقة تانية كيف ممكن نحسب ال return | |
| 76 | |
| 00:06:44,590 --> 00:06:56,870 | |
| يعني احنا حكينا zero which is okay نفسني ممكن يعني | |
| 77 | |
| 00:06:56,870 --> 00:07:03,930 | |
| خسر خمسين مظبوط و بعدين بدأ بخمسين كسب كم؟ خمسين | |
| 78 | |
| 00:07:03,930 --> 00:07:09,440 | |
| طيب طب خمسين ماخص خمسين صفر صح؟طيب خلينا ن .. ن .. | |
| 79 | |
| 00:07:09,440 --> 00:07:16,020 | |
| ندورلكم بيها شوية هلأ احنا هخسر خمسين صح؟ طيب لو | |
| 80 | |
| 00:07:16,020 --> 00:07:21,360 | |
| جينا احنا قولنا minus fifty divided by one hundred | |
| 81 | |
| 00:07:21,360 --> 00:07:26,500 | |
| مظبوط لأن هو خسر خمسين على المية اللي هو البدأ | |
| 82 | |
| 00:07:26,500 --> 00:07:32,720 | |
| الاستثمار okay في الفترة الأولى كام خسر؟ minus | |
| 83 | |
| 00:07:32,720 --> 00:07:38,870 | |
| fifty percentطيب بالفترة التانية ربح fifty لكن بدل | |
| 84 | |
| 00:07:38,870 --> 00:07:42,970 | |
| السثوار بكام fifty إذا انجداش عمل one hundred | |
| 85 | |
| 00:07:42,970 --> 00:07:48,870 | |
| percent so if you do the average إذا احنا بحسب ال | |
| 86 | |
| 00:07:48,870 --> 00:07:53,510 | |
| average minus fifty plus one hundred divided by | |
| 87 | |
| 00:07:53,510 --> 00:07:59,350 | |
| two so it's equal twenty five percent سبحان | |
| 88 | |
| 00:07:59,350 --> 00:08:04,590 | |
| الله اه | |
| 89 | |
| 00:08:07,360 --> 00:08:14,220 | |
| Okay شوفوا كيف | |
| 90 | |
| 00:08:14,220 --> 00:08:23,820 | |
| سفر؟ minus fifty plus one hundred طيب guess ميهم | |
| 91 | |
| 00:08:23,820 --> 00:08:27,520 | |
| twenty | |
| 92 | |
| 00:08:27,520 --> 00:08:30,800 | |
| five percent طيب what is the difference between | |
| 93 | |
| 00:08:30,800 --> 00:08:35,270 | |
| the first one which is zeroand the second one | |
| 94 | |
| 00:08:35,270 --> 00:08:39,170 | |
| which is twenty five percent ايش الفرق بين الأولى | |
| 95 | |
| 00:08:39,170 --> 00:08:45,070 | |
| zero and twenty five percent يعني ايش الفرق بين | |
| 96 | |
| 00:08:45,070 --> 00:08:51,330 | |
| الأولى و التانية اه اه | |
| 97 | |
| 00:08:51,330 --> 00:08:54,750 | |
| what is the difference between the first one which | |
| 98 | |
| 00:08:54,750 --> 00:08:58,950 | |
| make zero percent and the second one which make | |
| 99 | |
| 00:08:58,950 --> 00:09:03,410 | |
| twenty five percent okay my second question is | |
| 100 | |
| 00:09:03,630 --> 00:09:07,650 | |
| which is correct؟ | |
| 101 | |
| 00:09:07,650 --> 00:09:12,830 | |
| مين الصح فيهم؟ so some people saying the first one | |
| 102 | |
| 00:09:12,830 --> 00:09:16,390 | |
| and other people saying the second one which is | |
| 103 | |
| 00:09:16,390 --> 00:09:20,890 | |
| the correct مين | |
| 104 | |
| 00:09:20,890 --> 00:09:26,070 | |
| الصح فيهم؟ zero percent or twenty five percent? so | |
| 105 | |
| 00:09:26,070 --> 00:09:29,130 | |
| some people saying zero percent others twenty five | |
| 106 | |
| 00:09:29,130 --> 00:09:32,150 | |
| percent okay تلتين صح yes | |
| 107 | |
| 00:09:42,740 --> 00:09:47,160 | |
| Okay this is right so in the first time we | |
| 108 | |
| 00:09:47,160 --> 00:09:50,000 | |
| consider all of the investment in just only one | |
| 109 | |
| 00:09:50,000 --> 00:09:55,120 | |
| period so we starting here and we ending here so | |
| 110 | |
| 00:09:55,120 --> 00:10:01,100 | |
| the average or the rate of return is one hundred | |
| 111 | |
| 00:10:01,100 --> 00:10:05,600 | |
| minus one hundredSo it is zero. This is the first | |
| 112 | |
| 00:10:05,600 --> 00:10:09,300 | |
| assumption. The second one is breaking down the | |
| 113 | |
| 00:10:09,300 --> 00:10:14,960 | |
| investment into periods يعني الفكرة التانية أننا | |
| 114 | |
| 00:10:14,960 --> 00:10:23,010 | |
| قسمنا الاستثمار ل periodsنبدأ هنا و ننتهي هنا ثم | |
| 115 | |
| 00:10:23,010 --> 00:10:29,730 | |
| نبدأ هنا و ننتهي هنا فا فا فا فا فا فا فا فا فا فا | |

| 00:10:45,330 --> 00:10:49,690 | |
| مين الصح فيهم as I said both of the calculations | |
| 123 | |
| 00:10:49,690 --> 00:10:55,370 | |
| are correct okay which is the arithmetic and which | |
| 124 | |
| 00:10:55,370 --> 00:11:00,110 | |
| is the geometric the one with zero is the | |
| 125 | |
| 00:11:00,110 --> 00:11:04,910 | |
| geometric الأولى with zero is geometric and the | |
| 126 | |
| 00:11:04,910 --> 00:11:09,290 | |
| one with the average is arithmetic الأولى اللى | |
| 127 | |
| 00:11:09,290 --> 00:11:13,260 | |
| احنا استخدمناه هي ال geometricwe average all of | |
| 128 | |
| 00:11:13,260 --> 00:11:16,580 | |
| the periods and considering them as a one period | |
| 129 | |
| 00:11:16,580 --> 00:11:23,320 | |
| this is a geometric and in the reading list ال | |
| 130 | |
| 00:11:23,320 --> 00:11:27,780 | |
| reading اللي أعطتكوا إياها قبل يومين it gives you | |
| 131 | |
| 00:11:27,780 --> 00:11:30,060 | |
| more explanation about the difference between | |
| 132 | |
| 00:11:30,060 --> 00:11:36,540 | |
| geometric and arithmetic في خمس صفحات أعطتكم إياهم | |
| 133 | |
| 00:11:36,540 --> 00:11:40,600 | |
| وموجودين المفروضين في المكتبة صح فالمفروض البنات | |
| 134 | |
| 00:11:40,600 --> 00:11:41,040 | |
| ياخدوهم | |
| 135 | |
| 00:11:43,990 --> 00:11:47,690 | |
| أنا حكيت في أربع صفحات خمس صفحات أعطيتهم للبنات | |
| 136 | |
| 00:11:47,690 --> 00:11:52,090 | |
| يوم تلتينين هدول بيوضحوا ال arithmetic و ال | |
| 137 | |
| 00:11:52,090 --> 00:11:56,290 | |
| geometric فتاخدهم من المكتب هم موجودين okay تركتهم | |
| 138 | |
| 00:11:56,290 --> 00:12:02,730 | |
| في المكتب صح؟ اه okay اذا the one the geometric | |
| 139 | |
| 00:12:02,730 --> 00:12:09,790 | |
| the geometric is equal zero and the arithmetic is | |
| 140 | |
| 00:12:09,790 --> 00:12:13,450 | |
| equal twenty five percentانتبهوا، generally | |
| 141 | |
| 00:12:13,450 --> 00:12:19,510 | |
| speaking the result of arithmetic is greater than | |
| 142 | |
| 00:12:19,510 --> 00:12:25,110 | |
| the result of geometric في كل الحلات يا .. في كل | |
| 143 | |
| 00:12:25,110 --> 00:12:29,410 | |
| الحلات لما نحسب ال arithmetic، pay attention here | |
| 144 | |
| 00:12:29,410 --> 00:12:34,270 | |
| in all cases when we calculate the arithmetic and | |
| 145 | |
| 00:12:34,270 --> 00:12:38,570 | |
| when we calculate the geometric, arithmetic is | |
| 146 | |
| 00:12:38,570 --> 00:12:42,210 | |
| greater than geometricالجواب تبع ال arithmetic | |
| 147 | |
| 00:12:42,210 --> 00:12:45,730 | |
| بيكون أعلى من الجواب تبع ال geometric انتبهوا يعني | |
| 148 | |
| 00:12:45,730 --> 00:12:50,170 | |
| هذا ممكن يكون في أسئلة عليه ال question is why | |
| 149 | |
| 00:12:50,170 --> 00:12:52,630 | |
| there is a difference between geometric and | |
| 150 | |
| 00:12:52,630 --> 00:12:56,970 | |
| arithmetic؟ ليش في فرق بين ال geometric زي ما احنا | |
| 151 | |
| 00:12:56,970 --> 00:13:04,290 | |
| شوفنا في 0% او في 25%؟خلّينا احنا نشرح ال | |
| 152 | |
| 00:13:04,290 --> 00:13:07,770 | |
| geometric و بعدين نرجع to answer this question why | |
| 153 | |
| 00:13:07,770 --> 00:13:12,210 | |
| there is a difference between geometric and | |
| 154 | |
| 00:13:12,210 --> 00:13:17,230 | |
| arithmetic write down this question and just | |
| 155 | |
| 00:13:17,230 --> 00:13:19,990 | |
| remind me to answer this question at the end of | |
| 156 | |
| 00:13:19,990 --> 00:13:24,750 | |
| this class يعني بس ذكروني ان احنا نجاوبكم السؤال | |
| 157 | |
| 00:13:24,750 --> 00:13:31,410 | |
| هذا في نهاية ال class okay nowنحن نعرف كيف نتخيل | |
| 158 | |
| 00:13:31,410 --> 00:13:35,370 | |
| الارثماتيك نحن نعرف كيف نتخيل الارثماتيك فقط | |
| 159 | |
| 00:13:35,370 --> 00:13:45,170 | |
| لأذكركم الارثماتيك هو اكتشاف R مقال M هذا هو | |
| 160 | |
| 00:13:45,170 --> 00:13:50,650 | |
| الارثماتيك وأعطيكم مثلًا كيف نتخيل الارثماتيك الآن | |
| 161 | |
| 00:13:50,650 --> 00:13:56,730 | |
| كيف نتخيل الجيومتريك أولًاto calculate the | |
| 162 | |
| 00:13:56,730 --> 00:14:00,110 | |
| geometrics we have to calculate the terminal | |
| 163 | |
| 00:14:00,110 --> 00:14:04,170 | |
| values terminal values what is terminal values | |
| 164 | |
| 00:14:04,170 --> 00:14:08,830 | |
| means terminal values means terminal values لنحسب | |
| 165 | |
| 00:14:08,830 --> 00:14:14,430 | |
| ال terminal values يعني اللي هو العواقد للفترة | |
| 166 | |
| 00:14:14,430 --> 00:14:20,910 | |
| كلها مع بعض so احنا كنا نسوي بال .. بال .. ب | |
| 167 | |
| 00:14:20,910 --> 00:14:25,310 | |
| summation of R كنا ايش نسوي لو كان عندى عدة فترات | |
| 168 | |
| 00:14:26,550 --> 00:14:30,910 | |
| نشبعهم و نقسمهم أقصى فانسوا نشوف اللي هو إذا كان | |
| 169 | |
| 00:14:30,910 --> 00:14:38,370 | |
| عندي R1 plus R2 plus R3 okay till Rn divided by N | |
| 170 | |
| 00:14:38,370 --> 00:14:43,610 | |
| so this is still the arithmetic but in the | |
| 171 | |
| 00:14:43,610 --> 00:14:46,970 | |
| geometric the first thing we have to calculate the | |
| 172 | |
| 00:14:46,970 --> 00:14:47,770 | |
| terminal value | |
| 173 | |
| 00:14:50,630 --> 00:14:54,950 | |
| instead of summation of R because we consider this | |
| 174 | |
| 00:14:54,950 --> 00:15:00,190 | |
| as a one period بنحسبها كلها as a one period so we | |
| 175 | |
| 00:15:00,190 --> 00:15:04,010 | |
| don't need to multiply بنزمش ان احنا نعمل multiply | |
| 176 | |
| 00:15:04,010 --> 00:15:12,350 | |
| so what is what we can do then one R one times one | |
| 177 | |
| 00:15:12,350 --> 00:15:21,680 | |
| R two divided by one sorry times one R three oneR4 | |
| 178 | |
| 00:15:21,680 --> 00:15:25,520 | |
| 1R | |
| 179 | |
| 00:15:25,520 --> 00:15:29,420 | |
| M ثم | |
| 180 | |
| 00:15:29,420 --> 00:15:41,060 | |
| بعد ان نفعل هذا نحصل على النتائج نضربهم | |
| 181 | |
| 00:15:41,060 --> 00:15:45,000 | |
| نضربهم | |
| 182 | |
| 00:15:45,000 --> 00:15:49,400 | |
| بس نجمعهم واحد زائدبنضربهم في بعض وبعدين اللي | |
| 183 | |
| 00:15:49,400 --> 00:15:53,080 | |
| بنيجي بنقول ال terminal value كل ال terminal value | |
| 184 | |
| 00:15:53,080 --> 00:16:02,880 | |
| هذه one على n minus one هناخد مثال هذا | |
| 185 | |
| 00:16:02,880 --> 00:16:09,520 | |
| مهم اكتبيه اكتبيه طيب ناخد المثال فاكتبوا المثال | |
| 186 | |
| 00:16:09,520 --> 00:16:12,980 | |
| اللي اعطيتوايا على ال arithmetic اعطونيه عشان نحله | |
| 187 | |
| 00:16:12,980 --> 00:16:14,700 | |
| على ال geometric | |
| 188 | |
| 00:16:20,540 --> 00:16:31,580 | |
| الأولى 9% 10 12 8 5 5 okay | |
| 189 | |
| 00:16:31,580 --> 00:16:35,420 | |
| طيب | |
| 190 | |
| 00:16:35,420 --> 00:16:41,260 | |
| هلا نحسبها بال geometric نحسبها | |
| 191 | |
| 00:16:41,260 --> 00:16:46,240 | |
| بالاش بال geometric just multiply this just apply | |
| 192 | |
| 00:16:46,240 --> 00:16:50,400 | |
| this equation بس يعني نطبخ ال equationvery simple | |
| 193 | |
| 00:16:50,400 --> 00:17:08,660 | |
| يعني 1.09 x 1.10 x 1.12 x 1.8 x 1.5 خلصولي يا هادى | |
| 194 | |
| 00:17:08,660 --> 00:17:12,760 | |
| بنات بد الكل يكون معايا على حسبة please رجاء كلكوا | |
| 195 | |
| 00:17:12,760 --> 00:17:13,880 | |
| يكونوا معاكم على حسبة | |
| 196 | |
| 00:17:20,020 --> 00:17:25,240 | |
| نشوف طب ماشي نشوف طلعولي | |
| 197 | |
| 00:17:25,240 --> 00:17:31,360 | |
| جواب يا بنات خمسة point متأكد؟ غلط انا متأكد so | |
| 198 | |
| 00:17:31,360 --> 00:17:36,260 | |
| it's one point five طيب one point five ايش القانون | |
| 199 | |
| 00:17:36,260 --> 00:17:43,380 | |
| بيحكي؟ one point five بنحط the power of واحد على n | |
| 200 | |
| 00:17:43,380 --> 00:17:49,010 | |
| ال n قداش واحد اتنى اتلاتة اربعة خمسةنقص واحد عشان | |
| 201 | |
| 00:17:49,010 --> 00:17:52,350 | |
| نجيب one point five بقى هو واحد على خمسة كيف | |
| 202 | |
| 00:17:52,350 --> 00:17:58,490 | |
| نعملها تساوي جزر الخامس ل واحد point five minus | |
| 203 | |
| 00:17:58,490 --> 00:18:04,610 | |
| one يعني ممكن إذا حد مش عارف ممكن يجيب كم بيطلع | |
| 204 | |
| 00:18:04,610 --> 00:18:09,310 | |
| ناقص واحد تمانية بالمائية تمانية بالمائية تمانية | |
| 205 | |
| 00:18:09,310 --> 00:18:13,650 | |
| بالمائية اكيد اه طب فاكرين انتوا الجواب تبع الألف | |
| 206 | |
| 00:18:13,650 --> 00:18:14,290 | |
| متى كام طلع | |
| 207 | |
| 00:18:23,650 --> 00:18:27,410 | |
| طيب لأ لأ لأ خلّيني أقول حتة حتة، كم بالظبط طلع ال | |
| 208 | |
| 00:18:27,410 --> 00:18:33,830 | |
| arithmetic؟ عدول ال arithmetic، بسرعة بالظبط، | |
| 209 | |
| 00:18:33,830 --> 00:18:38,510 | |
| طيب انتبهوا هال arithmetic عندما نعطيه رمز A، طلع | |
| 210 | |
| 00:18:38,510 --> 00:18:41,230 | |
| تمانية point تمانية، و ال geometric عندما نعطيه | |
| 211 | |
| 00:18:41,230 --> 00:18:47,490 | |
| رمز G، بطلع تمانية point سبعة، إيش بتلاحظوا؟ | |
| 212 | |
| 00:18:51,370 --> 00:18:54,410 | |
| مش بتلاحظوا البنات التانية الوراق؟ إيش رأيكم؟ اللي | |
| 213 | |
| 00:18:54,410 --> 00:19:02,290 | |
| قدام سعادة؟ أه وردة، مظبوط؟ أه إيش رأيك؟ ليش .. | |
| 214 | |
| 00:19:02,290 --> 00:19:10,730 | |
| إيش بتلاحظي فيه جواب A و B؟ مفيش افتلاع في كتير، | |
| 215 | |
| 00:19:10,730 --> 00:19:19,160 | |
| بتعرف ليش؟ مين بيقدر يجاوبني؟هذه ملاحظة .. ملاحظة | |
| 216 | |
| 00:19:19,160 --> 00:19:23,920 | |
| تانية .. which is greater than .. ال arithmetic is | |
| 217 | |
| 00:19:23,920 --> 00:19:26,760 | |
| greater than .. طب إذا في الامتحان طالع عندك ال | |
| 218 | |
| 00:19:26,760 --> 00:19:30,840 | |
| geometric is greater than arithmetic ..معناة كلها | |
| 219 | |
| 00:19:30,840 --> 00:19:35,080 | |
| بدون ما أطلع بالتصريح ..شغل غلط صح؟ ال arithmetic | |
| 220 | |
| 00:19:35,080 --> 00:19:40,940 | |
| طيب .. you remember when I ask you .. to ask me | |
| 221 | |
| 00:19:40,940 --> 00:19:46,230 | |
| why there is a difference .. ليش فيه فرق؟you know | |
| 222 | |
| 00:19:46,230 --> 00:19:50,090 | |
| why there is a difference نسبة الخطأ نسبة الخطأ ال | |
| 223 | |
| 00:19:50,090 --> 00:19:56,290 | |
| error what it means نسبة الخطأ اه فاكرين احنا | |
| 224 | |
| 00:19:56,290 --> 00:20:01,090 | |
| حكينا المحاضرة الفاترة حكينا عن risk اذا if | |
| 225 | |
| 00:20:01,090 --> 00:20:06,010 | |
| اتطلعوا على الأرقام خلينا نتطلعوا لحظة على الأرقام | |
| 226 | |
| 00:20:06,010 --> 00:20:10,390 | |
| شوفوا في الأرقام الأرقام متقاربين يعني لو أجينا | |
| 227 | |
| 00:20:10,390 --> 00:20:15,100 | |
| أخدنا مثال مثلا هذا case one أخدنا case twofor | |
| 228 | |
| 00:20:15,100 --> 00:20:20,040 | |
| instance أخدنا twelve percent twenty percent five | |
| 229 | |
| 00:20:20,040 --> 00:20:24,960 | |
| percent one percent و fifty percent إيش رايكوا | |
| 230 | |
| 00:20:24,960 --> 00:20:29,140 | |
| بالأرقام هذه؟ فالخطأ عالي كتير أو بيسموها ال risk | |
| 231 | |
| 00:20:29,140 --> 00:20:35,680 | |
| is great شوي شوي عشان أنا فهمي بسيط كتير هلأ إذا | |
| 232 | |
| 00:20:35,680 --> 00:20:40,360 | |
| أحنا عسبنا ال arithmetic و ال geometric لهذه هلاقي | |
| 233 | |
| 00:20:40,360 --> 00:20:43,320 | |
| there is a big gap between the arithmetic and | |
| 234 | |
| 00:20:43,320 --> 00:20:50,190 | |
| geometricwhat we conclude in this when we face up | |
| 235 | |
| 00:20:50,190 --> 00:20:54,790 | |
| a stock a particular stock with a higher risk we | |
| 236 | |
| 00:20:54,790 --> 00:20:57,790 | |
| will find that the arithmetic is far away from the | |
| 237 | |
| 00:20:57,790 --> 00:21:02,810 | |
| geometric يعني إذا كان عندى سهم كتير مخاطرته عالى | |
| 238 | |
| 00:21:02,810 --> 00:21:06,040 | |
| هنلاقي ال arithmetic بعيدة عن ال geometricwhen | |
| 239 | |
| 00:21:06,040 --> 00:21:10,500 | |
| they .. when they .. a particular stock has a | |
| 240 | |
| 00:21:10,500 --> 00:21:13,460 | |
| minimum risk it means the arithmetic .. arithmetic | |
| 241 | |
| 00:21:13,460 --> 00:21:17,100 | |
| become closer and closer to the geometric بتكون | |
| 242 | |
| 00:21:17,100 --> 00:21:20,420 | |
| جريبة كتير على ال geometric طيب so the difference | |
| 243 | |
| 00:21:20,420 --> 00:21:25,060 | |
| between them is the risk الفرق بينهم هو ال risk | |
| 244 | |
| 00:21:25,060 --> 00:21:29,920 | |
| okay اعطيني ال .. ال .. ال .. انا اعطيتكم اياها | |
| 245 | |
| 00:21:29,920 --> 00:21:32,880 | |
| المرة الفاتة الشرط طبعا عنكم مصور | |
| 246 | |
| 00:21:36,270 --> 00:21:41,090 | |
| ال chapter تبعكم موجود المصور؟ اعطيني ال chapter | |
| 247 | |
| 00:21:41,090 --> 00:21:48,270 | |
| ال chapter okay عشان تتابعوا معايا انتوا في صفحه | |
| 248 | |
| 00:21:48,270 --> 00:21:59,630 | |
| في صفحه 132 التقصير تبعه okay تفضلي يا عمال okay | |
| 249 | |
| 00:21:59,630 --> 00:22:04,470 | |
| هلا طب اذا the difference between this and this | |
| 250 | |
| 00:22:04,470 --> 00:22:11,180 | |
| انت تبقى اناالفرق بين ال arithmetic و ال geometric | |
| 251 | |
| 00:22:11,180 --> 00:22:18,800 | |
| هو ال risk خلينا نعملكوا اختبار بسيط عشان نتأكد ان | |
| 252 | |
| 00:22:18,800 --> 00:22:23,580 | |
| انتوا in our standard | |
| 253 | |
| 00:22:32,680 --> 00:22:36,940 | |
| حكينا إذا ال geometric زي ما هو موجودة في الصفحة | |
| 254 | |
| 00:22:36,940 --> 00:22:41,760 | |
| 132 | |
| 255 | |
| 00:22:41,760 --> 00:22:49,260 | |
| ال geometric بتساوي ال arithmetic minus اللي هو ال | |
| 256 | |
| 00:22:49,260 --> 00:22:53,100 | |
| risk صح؟ how we can calculate risk؟ | |
| 257 | |
| 00:22:57,080 --> 00:23:01,020 | |
| لأ خلينا احنا انا انا انا انا انا انا انا انا انا | |

| انا انا | |
| 268 | |
| 00:23:23,620 --> 00:23:31,190 | |
| ااتبعوا على المثال، المثال بسيط كام | |
| 269 | |
| 00:23:31,190 --> 00:23:36,930 | |
| الفرق بين الخمسة والعشرة؟ | |
| 270 | |
| 00:23:36,930 --> 00:23:42,810 | |
| مين .. نختار مين؟ what is the difference between | |
| 271 | |
| 00:23:42,810 --> 00:23:43,590 | |
| five and ten? | |
| 272 | |
| 00:23:46,630 --> 00:23:52,990 | |
| five .. five إيش الفرق بين .. يعني إيش الفرق بين | |
| 273 | |
| 00:23:52,990 --> 00:23:58,300 | |
| خمسة ما هو الفرق بين خمسة وعشرة؟خمسة which is | |
| 274 | |
| 00:23:58,300 --> 00:24:06,100 | |
| wrong سالب خمسة which is also wrong غلط أربعة مين | |
| 275 | |
| 00:24:06,100 --> 00:24:11,340 | |
| يلا شايفين اللي .. الفرق بين الخمسة و العشرة كام؟ | |
| 276 | |
| 00:24:11,340 --> 00:24:17,680 | |
| ستة طيب أبسطلكوا إياها don't forget we are talking | |
| 277 | |
| 00:24:17,680 --> 00:24:21,560 | |
| about investments احنا بنحكي عن إيه؟ لو اتنين | |
| 278 | |
| 00:24:21,560 --> 00:24:26,280 | |
| شرايكشرايك يعني شركة اتنين مش تركيين مع بعض في | |
| 279 | |
| 00:24:26,280 --> 00:24:32,780 | |
| شركة partners partners مقصود فيها متزوجين يعني بس | |
| 280 | |
| 00:24:32,780 --> 00:24:38,280 | |
| اتنين مش تركيين في شركة و a half half يعني نص من | |
| 281 | |
| 00:24:38,280 --> 00:24:44,820 | |
| نص و ليكن مثلا الزوج و الزوجة مش تركيين okay إجا | |
| 282 | |
| 00:24:44,820 --> 00:24:52,740 | |
| اتفقوا مع بعضال profits نسيبه هان ال profits | |
| 283 | |
| 00:24:52,740 --> 00:24:56,860 | |
| عملوها عشرين دولار عشرين ألف دولار جداش المفروض | |
| 284 | |
| 00:24:56,860 --> 00:25:03,740 | |
| عشرة عشرة عشرة عشرة عشرة صح طيب إجى الرجل جال | |
| 285 | |
| 00:25:03,740 --> 00:25:06,820 | |
| للزوجة أنا عندي عباء كتير و كذا و إشي و خليني أنا | |
| 286 | |
| 00:25:06,820 --> 00:25:11,760 | |
| أخد منك ألف دولار قالت له okay ده إنه أنت عندك | |
| 287 | |
| 00:25:11,760 --> 00:25:18,400 | |
| عباء كتير فصار تسعة أحد عشر صار أحد عشر تسعةwhat | |
| 288 | |
| 00:25:18,400 --> 00:25:20,920 | |
| is the difference between them؟ كده الفرق بينهم؟ | |
| 289 | |
| 00:25:20,920 --> 00:25:31,140 | |
| اتنين غلط شايفين كيف؟ لينا مش عارفة مش مبسوط الف | |
| 290 | |
| 00:25:31,140 --> 00:25:39,640 | |
| how you calculate this؟ كيف حسبتيها؟ | |
| 291 | |
| 00:25:39,640 --> 00:25:44,540 | |
| الفرق بينهم الف طب ليش انتوا لما اجيتوا حكيتوا | |
| 292 | |
| 00:25:44,540 --> 00:25:49,730 | |
| الفرق بين الخمسة والعشرة قلتوا خمسة؟الفرق بين | |
| 293 | |
| 00:25:49,730 --> 00:25:53,490 | |
| الخمسة والعشرة مش خمسة الفرق بين الخمسة والعشرة هي | |
| 294 | |
| 00:25:53,490 --> 00:25:59,570 | |
| اتنين و نص طيب | |
| 295 | |
| 00:25:59,570 --> 00:26:05,490 | |
| خلّينا .. خلّينا نرجع للمثال .. خلّينا نرجع للمثال | |
| 296 | |
| 00:26:05,490 --> 00:26:14,270 | |
| عشان تفهم المعادلة هجيت من أن أعدل في المعادلة فهم | |
| 297 | |
| 00:26:14,270 --> 00:26:18,640 | |
| المثال هذا؟التنين اتفقوا خمسين في المية خمسين في | |
| 298 | |
| 00:26:18,640 --> 00:26:21,860 | |
| المية عشرة دولار عشرة تلاف عشرة تلاف صح؟ إيجي .. | |
| 299 | |
| 00:26:21,860 --> 00:26:25,320 | |
| إيجي الزوج حاكي للزوجة أنا بتعرفي كيف أولاد و كذا | |
| 300 | |
| 00:26:25,320 --> 00:26:28,960 | |
| و أنا اللي بصرف و إشي يلا تقولوا okay بعطيك ألف | |
| 301 | |
| 00:26:28,960 --> 00:26:33,960 | |
| دولار مني فراحت أخدت ألف دولار منها وعطتها لزوجها | |
| 302 | |
| 00:26:33,960 --> 00:26:37,780 | |
| صار هو معاه أحد عاش و هي معاه تسعة what is the | |
| 303 | |
| 00:26:37,780 --> 00:26:40,600 | |
| difference between them two thousands مش two | |
| 304 | |
| 00:26:40,600 --> 00:26:43,880 | |
| thousands الفرق بين أتهم ألفين لأ الفرق بين أتهم | |
| 305 | |
| 00:26:43,880 --> 00:26:49,920 | |
| ألفالفرق بينهم الف يعني if the husband give the | |
| 306 | |
| 00:26:49,920 --> 00:26:53,480 | |
| one thousand back to his wife إذا رجع الألف دولار | |
| 307 | |
| 00:26:53,480 --> 00:27:00,320 | |
| لزوجته بيصيروا عشرة عشرة صح ولا لأ؟ okay طيب | |
| 308 | |
| 00:27:00,320 --> 00:27:08,410 | |
| ابتدوا هنا ابتدوا هنا هلأ هاي خمسة وهي عشرةعشان | |
| 309 | |
| 00:27:08,410 --> 00:27:12,110 | |
| انا اقدر احسب الفرق بين ال .. ال geometric و بين | |
| 310 | |
| 00:27:12,110 --> 00:27:15,590 | |
| ال .. the same .. the same thing، نفس الفكرة، هاي | |
| 311 | |
| 00:27:15,590 --> 00:27:18,510 | |
| خمسة و أنا عشرة، الفرق بيبقى تقولها اتنين و نص، | |
| 312 | |
| 00:27:18,510 --> 00:27:21,430 | |
| صح؟ طيب، لو أعطينا الخمسة و قولنا لها يا خمسة خدّي | |
| 313 | |
| 00:27:21,430 --> 00:27:25,330 | |
| هاي اتنين و نص، فكم هتصير؟ طب اتنين و نص جيبناهم | |
| 314 | |
| 00:27:25,330 --> 00:27:29,050 | |
| من وين؟ من العشرة، اذا العشرة قولنا لها ناقص اتنين | |
| 315 | |
| 00:27:29,050 --> 00:27:36,890 | |
| و نص، هتصير سبعة و نصمظبوط ولا لأ؟ طيب خلينا نهنا | |
| 316 | |
| 00:27:36,890 --> 00:27:41,590 | |
| اللي جاوبت خمسة او مين اللي جاوب خمسة؟ لو احنا | |
| 317 | |
| 00:27:41,590 --> 00:27:46,950 | |
| جاوبنا خمسة قلنا الخمسة قابلنا من الخمسة فصارت | |
| 318 | |
| 00:27:46,950 --> 00:27:51,470 | |
| خمسة زي الخمسة عشرة اذا هذه صارت سفر وهذه صارت | |
| 319 | |
| 00:27:51,470 --> 00:27:56,570 | |
| عشرة كيف صاروا متساوين عاد؟ طيب | |
| 320 | |
| 00:28:03,570 --> 00:28:09,350 | |
| So again إذا ال geometric انتبهوا للمعادلة أنا ليش | |
| 321 | |
| 00:28:09,350 --> 00:28:12,570 | |
| أعطلكوا الكلام هذا انتبهوا للمعادلة ال geometric | |
| 322 | |
| 00:28:12,570 --> 00:28:16,550 | |
| بتساوي arithmetic minus sigma تربيع which is wrong | |
| 323 | |
| 00:28:16,550 --> 00:28:25,450 | |
| المفروض تكون half of sigma تربيع البنات | |
| 324 | |
| 00:28:25,450 --> 00:28:28,370 | |
| الكلام هذا اللي بنوا عليه بنوا عليه الكلام هذا | |
| 325 | |
| 00:28:28,370 --> 00:28:33,380 | |
| عملوا Nobel Prize عملوا إيش؟نوبل برايس عملوا جائزة | |
| 326 | |
| 00:28:33,380 --> 00:28:38,840 | |
| نوبل اللي بيشتغلوا في المواضيع هذه اللي هو | |
| 327 | |
| 00:28:38,840 --> 00:28:49,460 | |
| ماركويتس و ويليام شارب اذا | |
| 328 | |
| 00:28:49,460 --> 00:28:55,860 | |
| الفرق بين ال geometric geometric is equal to | |
| 329 | |
| 00:28:55,860 --> 00:28:59,820 | |
| arithmetic minus half of sigma two أو sigma تربيه | |
| 330 | |
| 00:29:01,580 --> 00:29:07,120 | |
| إذا نعرفنا why it is half، نعرفنا ليش half، نصها، | |
| 331 | |
| 00:29:07,120 --> 00:29:11,180 | |
| لأن زي ما حكينا الآن الفرق بين الخمسة والعشرة مش | |
| 332 | |
| 00:29:11,180 --> 00:29:14,430 | |
| زي ما احنا بنعرف أنه خمسةلأن إحنا في ال | |
| 333 | |
| 00:29:14,430 --> 00:29:17,770 | |
| investments زي ما شوفنا بين الزوج والزوجة when | |
| 334 | |
| 00:29:17,770 --> 00:29:21,550 | |
| they invest in the company it doesn't mean .. when | |
| 335 | |
| 00:29:21,550 --> 00:29:24,950 | |
| the wife give her husband one thousand dollar it | |
| 336 | |
| 00:29:24,950 --> 00:29:27,310 | |
| doesn't mean that the difference is two thousands | |
| 337 | |
| 00:29:27,310 --> 00:29:31,230 | |
| the difference is one thousand if the husband give | |
| 338 | |
| 00:29:31,230 --> 00:29:34,990 | |
| back one thousand to his wife it means they have | |
| 339 | |
| 00:29:34,990 --> 00:29:38,250 | |
| one thousand for each يعني الابتنين هيكون عندهم | |
| 340 | |
| 00:29:38,250 --> 00:29:44,660 | |
| ten thousands مظبوط ولا لأ؟ إيش طبيعي؟يعني إذا .. | |
| 341 | |
| 00:29:44,660 --> 00:29:52,020 | |
| إذا أعطته أربعة ألف دولار، | |
| 342 | |
| 00:29:52,020 --> 00:29:56,900 | |
| جداش الفرق بينهم حصيل؟ أعطته أربعة ألف دولار، حصيل | |
| 343 | |
| 00:29:56,900 --> 00:30:01,060 | |
| هان كام؟ أربعة عشر ألف، و هان كام؟ ستة آف، الفرق | |
| 344 | |
| 00:30:01,060 --> 00:30:05,640 | |
| بينهم كام؟أه اربعة طول عشان نقل ستة كام تمانية اذا | |
| 345 | |
| 00:30:05,640 --> 00:30:09,500 | |
| هالفرق بين اتنين تمانية ع اتنين اذا الفرق اربعة | |
| 346 | |
| 00:30:09,500 --> 00:30:13,140 | |
| تلاف دولار لاربعة تلاف دولار لو احنا رجعنا الأربعة | |
| 347 | |
| 00:30:13,140 --> 00:30:18,840 | |
| هيصيروا عشرة عشرة okay فهذا القانون | |
| 348 | |
| 00:30:29,230 --> 00:30:32,030 | |
| So you understand what it means geometric and | |
| 349 | |
| 00:30:32,030 --> 00:30:41,970 | |
| arithmetic كيف؟ بطعة sigma تربيه مص sigma تربيه في | |
| 350 | |
| 00:30:41,970 --> 00:30:46,170 | |
| الامتحان او في الحياة ايش هنسويلك هنعطيك ال | |
| 351 | |
| 00:30:46,170 --> 00:30:49,530 | |
| arithmetic هنعطيك ال sigma تربيه هنقولك calculate | |
| 352 | |
| 00:30:49,530 --> 00:30:56,780 | |
| the geometric موجود عندكم بالبال .. بال reading | |
| 353 | |
| 00:30:56,780 --> 00:30:58,960 | |
| list اللي أنا أعطيتكوا إياها موجود عندكم مثال | |
| 354 | |
| 00:30:58,960 --> 00:31:05,680 | |
| بتحلو طبعا okay إذا الفرق بين ال geometric و ال .. | |
| 355 | |
| 00:31:05,680 --> 00:31:10,540 | |
| و ال arithmetic هو فرق بال .. بال إيش؟ بال risk و | |
| 356 | |
| 00:31:10,540 --> 00:31:17,140 | |
| أي risk مش ال risk كله نص ال risk okay half of the | |
| 357 | |
| 00:31:17,140 --> 00:31:19,440 | |
| risk okay | |
| 358 | |
| 00:31:23,820 --> 00:31:29,180 | |
| هذا حساب العائد طبعا قالوا اذا قلنا اذا قلنا اتنين | |
| 359 | |
| 00:31:29,180 --> 00:31:33,380 | |
| صح ال arithmetic لكن ال arithmetic is more common | |
| 360 | |
| 00:31:33,380 --> 00:31:38,320 | |
| than any other than any other calculations يعني | |
| 361 | |
| 00:31:38,320 --> 00:31:40,800 | |
| أكثر شيء هو ال arithmetic من other calculations | |
| 362 | |
| 00:31:40,800 --> 00:31:45,540 | |
| okay طيب | |
| 363 | |
| 00:31:45,540 --> 00:31:50,800 | |
| هاي طبعا أخدتواها المعادلة شرحنا لكواياها why is | |
| 364 | |
| 00:31:50,800 --> 00:31:51,140 | |
| it geometric | |
| 365 | |
| 00:31:58,210 --> 00:32:01,990 | |
| بنا نحسب ال sigma تربيع أخدناها أظن ال sigma تربيع | |
| 366 | |
| 00:32:01,990 --> 00:32:06,510 | |
| كيف نحسبها اللي هو عندنا ال R minus R bar تربيه | |
| 367 | |
| 00:32:06,510 --> 00:32:12,610 | |
| على 1 divided by N عشان | |
| 368 | |
| 00:32:12,610 --> 00:32:18,630 | |
| نعمل نشيل ال bias طبعا نجيب الجزر على 1 N minus 1 | |
| 369 | |
| 00:32:18,630 --> 00:32:22,090 | |
| نجيب عند sharp ratio | |
