WebMay 26, 2015 · Anyways both variants have the same variance. So assuming we already know that E[X] = 1 p. Then the variance can be calculated as follows: Var[X] = E[X2] − (E[X])2 = E[X(X − 1)] + E[X] − (E[X])2 = E[X(X − 1)] + 1 p − 1 p2 So the trick is splitting up E[X2] into E[X(X − 1)] + E[X], which is easier to determine.
