The mean and variance of a binomial vari...

The mean and variance of a binomial variance with parameters `n` and `p` are 16 and 8 respectively. Find `P(X=0),P(X=1)a n dP(Xgeq2)dot`

Text Solution

Verified by Experts

Given,
`np=8`
`npq=16`
So,
`q=p=1/2` thus,
`n=32`
now,
`p(x=r)=n_(c_r)p^rq^(n-r)`
