Question

What are the mean and standard deviation of a binomial probability distribution with `n=8` and `p=7/29`?

Answer 1

mean`=56/29`
standard deviation`=(4sqrt(77))/29`

Explanation:

Given Binomial Probability Distribution
mean`=np=8*7/29=56/29`
standard deviation`=sqrt(np(1-p))=sqrt(8*7/29*22/29)=(4sqrt(77))/29`

God bless....I hope the explanation is useful.
