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

Show how Var(Xi) depends on p writing it as a function [tex]\sigma[/tex]^2(p)

3. The attempt at a solution

Var[Xi] = E[Xi^2] - E^2[Xi] = p-p^2 = p(1-p)

not sure where to go from here to get it in the form [tex]\sigma^2[/tex](p) ?
