Question

If the probability of buying a Ford is 0.3 and the probability of buying a car getting more than 20 miles per gallon is 0.4, what is the probability that they will buy both a Ford and a car getting more than 20 miles per gallon?

a. 0.12
b. 0.2
c. 0.3
d. 0.7

Answer 1

The probability of buying both a Ford and a car getting more than 20 miles per gallon is 0.12, which is option a.

Step-by-step explanation:

To find the probability of buying both a Ford and a car getting more than 20 miles per gallon, we multiply the probabilities of each event happening.

Probability of buying a Ford = 0.3

Probability of buying a car getting more than 20 mpg = 0.4

Probability of buying both a Ford and a car getting more than 20 mpg = (0.3) * (0.4) = 0.12

So, the probability is 0.12, which is option a.
