You can put this solution on YOUR website! In a standard deck of 52 cards,12 are face cards(king, queen, jack) Assume that five cards are selected with replacement out of a well-shuffled deck.
----------------------------------------
What is the probability of getting exactly three face cards::
(12C3*40C2)/52C5 = 0.0660
------------------------
What is the probability of getting at least one face card?
1 - P(no face cards)
= 1 - 40C5/52C5
= 1 - 0.2532
= 0.7468
