5. (7 points) Reginald Osborne Rigsby III is being dealt a five-card poker hand from a well-shuffled, stan- dard deck of cards. The first three cards that he is dealt are JO, JO, and 50. What is the probability that he will be dealt a full house? (Recall that a full house is two cards that form a pair and three cards that form a 3-of-a-kind, AND necessarily, of course, the pair and the 3-of-a-kind are of different ranks).gang
