Answer:
Heart: 1 in 4 chance
Ace: 1 in 13 chance
Explanation:
First we'll start with the probability of picking a heart.
There are four different suits in the deck: spades, clubs, diamonds, and hearts. Therefore, since hearts is one of the four there is a 1 in 4 chance he will pick hearts.
For the ace, we have to consider how many cards are in the deck and how many of them are aces. There are 52 cards in a standard playing card deck and 4 of them are aces. Therefore, since 4/52 = 2/36 = 13, there is a 1 in 13 chance that he will pick an ace.
Hope that helps!
