You can put this solution on YOUR website! four cards are randomly selected from a standard 52 card deck, what is the probability of getting 4 hearts or 4 cards lower than a 9, counting aces as 1?
--------------------
P(4 hearts or 4 cards <9) ?
# of hears: 13
# of cards < 9 : 32
# of hearts < 9: 8
---------------------------
P(4 hearts or 4 cards < 9)
= (13C4 + 32C4 - 8C4)/(52C4) = 0.1352....
