Jaque has a deck of 52 cards with 4 suits (hearts, spades, diamonds, and clubs), and each suit has cards numbered 1–13. What is the theoretical probability of him picking a heart from the deck of cards? The answer should be a fraction. Remember to simplify.

There are 13 hearts in the deck of 52 cards.

So, the theoretical probability of picking a heart from the deck of cards is:

Number of hearts / Total number of cards = 13/52 = 1/4

Therefore, the theoretical probability of picking a heart from the deck of cards is 1/4.
