There are are a total of 52 cards in the deck. Let's break it down into what types:

(a) Probability of King = 4/52

= 1/13

(b) Face card probability = 12/52

= 3/13

(c) Probability of Heart = 13/52

= 1/4

(d) Probability of face card and A = (12+4)/52

= 16/52

= 4/13

There you go!!! :)

- There are four Kings in a deck.
