What is the expected number of cards that need to be turned over in a regular 52 card deck in order to see the first ace?

This question is more easily answered in general. The expected number of cards in an n-card deck that need to be turned over to see the first of k cards is (n+1)/(k+1). In this case, n=52, k=4 (there are four aces) so the answer is 53/5 = 10.6.
