Let a be the set of five-card hands dealt from a 52-card deck, where the denominations of the five cards are all consecutive—for example, (7 of hearts, 8 of spades, 9 of spades, 10 of hearts, jack of diamonds). let b be the set of five-card hands where the suits of the five cards are all the same. how many outcomes are in the event a ∩ b?
