Problem

You are dealt a 13-card hand from a standard 52-card deck. Compare two conditional expectations:

(a) The expected number of aces in your hand given that it contains at least one ace.

(b) The expected number of aces in your hand given that it contains the ace of spades specifically.

Which is larger, and what are the two values?
