Problem Statement

You, your friend, and two strangers are sitting at a table. A standard 5252-card deck is randomly dealt into 44 piles of 1313 cards each, and each person at the table takes a pile. You look through your hand and see that you have one ace. Compute the probability that your friend’s hand contains the three remaining aces.
