Hi, i'm david and i'm going to help you and see your question.
00:03
Now let me bring up your question here.
00:06
In the question here, we're going to review about the binomial distribution.
00:10
Let me remind you that if the x that followed by the binomial with the n and the p.
00:16
And then the probability of the x equal to k, equal to the n choose k, and then b power k times 1 minus b power n minus k.
00:29
Also, the expected value of the x will equal to the n times p.
00:35
In this question here, we have the 79 % of the household had access to the internet.
00:41
So we will have the p equal to the 179.
00:44
In the question a, we're given an equal to 100.
00:49
And the question asked you to find the expected number of the household that will have the internet.
00:56
So if we call the x, it would equal to the number of the household.
00:59
Households that have the access to the internet...
