comment Find reduction formula using integration by parts
I don't understand how you've got from the second line to the third line which begins to look like the result needed.

comment Reduction formula
Integrating by parts twice for the second part seems difficult.

comment CDF and conditional probability
I seem to get $$ \int_0^{\infty} \lambda e^{tx-t\lambda} dx = [\frac{\lambda e^{tx-t\lambda}}{t}]_0^{\infty} $$ if $t$ is treated as a constant.

comment CDF and conditional probability
I seem to be dealing with a partial integral here. I am sure I am doing something wrong. Please take a look at this: $\int_0^{\inf} \lambda e^{-\lambda t} e^{Tx} dx$

comment CDF and conditional probability
$P(T>t)=1-(1-e^{-\lambda t})=e^{-\lambda t}$. If that is right, the rest of the proof is easy. Also please see my edit about the MGF.

comment Gambler tosses coin PGF
I know the definition but I don't know how to calculate it. I suggested the third central moment because that is one of the ways that you can do it, but I don't think that is the best way.
