<PRE><B>Question 480277</B>
From a 52 card deck, and choosing (flopping) three cards, what is the probability of getting an Ace or Jack or Seven? Or any combination (meaning that more than one of each could also be chosen) 
----
# of sets of 3 with NO ace,jack, or seven: 40C3
Total # of sets of 3 cards: 52C3 = 22100
-----
# of sets that contain one of more ace, jack, or seven: 52C3-40C3 =12220
--------------
P(set with one or more ace,jack, or seven) = 12220/22100 = 0.5529
