Hello,
I corrected some LaTeX errors and a typo in the way you defined q (it's the conditional probability, not the joint probability as you initially wrote). And your solution is perfect
Suppose and are both integer-valued random variables. Let
Show that
Solution
Consider
So
as
So
So our result is proven
