However, he also wants us to provide a verification technique on how to prove these formulas. I've looked in the book and there was nothing, and we've only gone over a few in class. This was assigned on the last class period and is due before the next class, so I'm really stuck and don't know where to go.

I work tonight and have class pretty much all day tomorrow, so I can't seek help elsewhere. Does anyone know of a good website or something where I can find this information? The distributions I have to "prove" are: Bernoulli, Binomial, Geometric, Hypergeometric, Negative Binomial, Poisson, and Uniform.

Thanks in advance!
