Hi, i'm david and i'm here to help you answering your question.

Now let me bring up your question here.
00:06
Now in this question we discuss about the binomial distribution.
00:11
If x follow the binomial with the n and the p, then the probability of the x equal to k, equal to the n choose k, p power k, times 1 minus p power and minus k.
00:25
Now in this question we are given the three probability here.
00:31
Here so the we will have technically will be the multi -binomial so we have this one will be the p1 p2 and the p3 for p1 we have a 0 .0 1 p2 1 p2 equal to the 0 .0 .0 0 4 p3 equal to 0 .95 and then we have n equal to 5 bit so n equal to 5 and it means that i'm not going to refer to this binomial but i will introduce to you the multi -binomial so if x follow the multi -so multi -binole with the np1 after the pk so in this case k equals 3 therefore the probability of the x here it will equal to the n and then with the k1, k2, k3, and then we have the p1 power k1, p2 power k2 times the pk power pk power k.

And it means like this, so in the part i want to find the probability that one bit has high distortion, one has moderate distortion, and three bits have low distortion.
02:08
So this will correspond to the high.
02:13
This will be moderate and the last one will be low.
02:19
So therefore, 25 probability that we have one high, then one moderate and then we have three low.
02:33
So this one will be from five we will choose one, one and three times with the high.
02:42
High we have the 0 .0 1, power 1.
02:46
For the moderate, we have the 0 .04, power 1...
