Independence of Random Variables
I'm reading this online book SticiGui and Excercise 19-6 says, in effect, the following:

Two five-card hands are dealt from a deck of cards without replacement. The random variables "The number of Aces in the first hand," and "The number of hearts in the second hand," are dependent. I don't see, how, though. Given that, say, the first hand has two aces, how could that influence the probability of any number of hearts in the second hand?

Do you usually play with a deck that does not contain the Ace of Hearts ....?
