Question

Suppose you draw a card from a regular deck of 52 cards.

a. What is the probability that you draw an ace?

b. What is the probability that you draw a spade?

Short answer

Hence, the probability of getting an ace is $\frac{1}{13}$

and the probability of getting spades is$\frac{1}{4}$

Step-by-step solution

Given information

Suppose you draw a card from a regular deck of 52 cards.

Explanation

a)Because there are four aces and 52 cards in the deck, the probability is:

$$\begin{gathered} p=\frac{4}{52} \\ p=\frac{1}{13} \end{gathered}$$

b) Because there are 13 spades and 52 cards in the deck, the probability is:

$$\begin{gathered} p=\frac{13}{52} \\ p=\frac{1}{4} \end{gathered}$$
