A pack of cards consists of 52 different cards. A dealer changes one of the cards for a second copy of another card in the pack and he then deals the cards to four players, giving thirteen to each.
What is the probability that one player has two identical cards?
I'm not sure how to do this, do we consider each player getting the same cards seperately then add those probabilities together? And if so, one we are consider each player, do we multiply by the probability of the other players getting normal cards?
