Hi everyone, welcome to the question.
00:03
So in this question, they have given n is equal to 95.
00:06
P is equal to 73 percentage.
00:09
We have to find probability that at 975 seats will germinate.
00:16
Now coming to the problem, using normal approximation.
00:25
Using normal approximation, our mean will be np.
00:38
And our standard deviation sigma will be square root of n multiplied by p multiplied by 1 minus square root of.
00:49
Okay.
00:50
So a mean will be n is from the question 95 multiplied by a p is 73 percentage which we will convert it into 0 .73.
01:02
So when you multiply, the answer is 69 .3.
01:06
Side.
01:07
Now our standard deviation sigma is sigma is equal to square root of again n is 95 p 0 .73 multiplied by 1 minus 0 .73 so square root of 95 multiplied by 0 .73 multiplied by 0 .27 so that is equal to square root of 1872 .45 so our sigma standard deviation is 43 .27...
