(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

For fixedn, are there values of p (0≤p≤1) for which V(X) = 0? Explain why this is so.

3. The attempt at a solution

For X~Bin(n,p), V(X)=np(1-p). So the only solutions for this equation are when p=0 or p=1. There are too many variables for me to keep track of and understand. Is p the probability of X occuring? And n is the number of trials in the experiment? If so, if the probability of X occuring is zero or one, how does that relate to variance of the outcomes of the experiments? I'm confused.
