# Math Help - [SOLVED] Proof of stats theorem

1. ## [SOLVED] Proof of stats theorem

2. Do you know the mean and variance of a binomial distribution?

3. Yes, we have worked with those a little. The mean is basically E(X) and variance is E(X^2) - E(x)^2. I am really not sure where to go from there, though... so, maybe I could take over after the first couple steps, but I am just not sure how to start.
