General case: X~B(n,p)
I could integrate the product of x and pmf from 1 to infinity and divide it by the integral of just pmf from 1 to infinity to find it, but I'm really stuck since I can't do it due to the sophisticated pmf function of binomial.
How can we find this expectation and Variance(X|X>1)?
Thank u
