A deck consists of playing cards that can have one of 12 suits and one of 6 ranks. A hand is a set of five cards randomly selected from the deck. How many hands are a four of a kind (four cards with the same rank but different suits, and a fifth card that is a different rank from the other four)? H = What is the probability of the hand being a four of a kind? +
