comment Conditional expectation of number of dice rolls
Now that I'm looking at it again, I'm having a harder time understanding where $EX$ came from than where $\mu_k$ came from. The recursive nature if $EX$ is hard to grapple

Can you elaborate more on how you came up with that expression for $\mu_k$? It does work, but I don't really understand where you got it from

Whoops, I'm sorry! I typed too fast...X and Y are random variables, not events. I'll fix that right now.

comment Conditional expectation of number of dice rolls
Ok, so then I'm just dealing with $\frac{P(X=x)}{P(Y=1)}$? But then $\sum_{x=1}^\infty x\frac{(5/6)^{x-1}(1/6)}{(1/6)} = \sum_{x=1}^\infty x(5/6)^{x-1} = 36$, which is not $7$
