I have a quick one. An example in a book im reading says (a) what is the probability of being delt four of a kind, that is, for aces, four kings, and so forth? (one standard 52 card deck) And they say "there are only 48 possible hands containing 4 aces; another 48 containing 4 kings etc. Thus there are 13*48 possible four-of-a-kind hands" There are 13 different cards, A-2-10-J-Q-K, doesnt that mean there are 13 possible four of a kind hands? What am I not seeing here...... Thank you.
