Hi, i'm david and i'm here to have you answering your question.
00:03
Now let me bring up your question here.
00:06
In the question here we are going to discuss about the binomial distribution.
00:11
Let me remind you that if the x that followed by the binomial with the n and the b, and then the probability of the x equal to k, equal to n choose k, b b, times 1 minus b, power n minus k.
00:27
In the question here we have the probability of the zobon that an applicant will not be able to repay his instrument loan.
00:35
So we have p equal to the 0 .25.
00:39
We have the n equal to the 40 loans.
00:42
So it will define the x equal to the number of the loans that will be defaulted.
01:04
So the far we will see x, it will follow by the binomial with the n equal to the 4.
01:10
And the p equals to the subon 25.
01:13
Now the question a, want to find the probability that there will be exactly three loans will be defaulted.
01:21
So x equal to the 3...
