comment Expectation related to Normal distribution and its density
I seem to get this to be true only when $\sigma< 1$... and that might sense somewhat.

You were probably too wasteful throwing away the $\Phi$ term.

comment The mathematical odds of winning a hand in poker with two boards
Nevertheless I actually don't think ^ matters much. The losing player has a better chance of keeping the money (so does the winning player).

comment The mathematical odds of winning a hand in poker with two boards
This would surely also depend on many more things: on how many overcards does the player with a flush draw have? whether the player with the pair is holding one of the outs for the flush? Was the pair a pocket pair? etc. You should give a specific combination of cards, then I am happy to calculate these for you.

comment Determine the law of $F^{-1}(U)$, $U$ uniformly distributed on $[0,1]$
@OBDA not generally, because the function $F$ is only known to be right-continuous (by definition $F(x)=P(X\leq x)$)
