Lucy 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 her picking a 4 from the deck of cards? The answer should be a fraction. Remember to simplify
There are 4 "4" cards in a deck of 52 cards.
So the probability of Lucy picking a 4 card is:
\[ P(\text{picking a 4}) = \frac{4}{52} = \frac{1}{13} \]
Therefore, the theoretical probability of Lucy picking a 4 card is \(\frac{1}{13}\).
