Chapter 39: Q 4 Exercise (page 1136)

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

Expert verified

Hence, the probability of getting an ace is 113

and the probability of getting spades is14

Step by step solution

01

Given information

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

02

Explanation

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

p=452p=113

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

p=1352p=14
