Using a standard deck of cards (52 cards with 13 hearts, 13, spades, 13 clubs and 13 diamonds; each suit contains numbers 2-10 and includes a jack, queen, king, and ace) determine the probability of the event. The probability of a face card:
3/13
The probability of the number 5 :
1/13
The probability of a non-face card:
9/13

The probability of a face card is 3/13 because there are 12 face cards in a deck (4 jacks, 4 queens, and 4 kings) and 52 total cards in a deck.

The probability of the number 5 is 1/13 because there is only one card with the number 5 in each suit (5 of hearts, 5 of spades, 5 of clubs, and 5 of diamonds) and 52 total cards in a deck.

The probability of a non-face card is 9/13 because there are 40 non-face cards in a deck (13 hearts, 13 spades, 13 clubs, and 1 non-face diamond card) and 52 total cards in a deck.
