Assume that you are about to buy a car. There is a probability of 0.4 that you will purchase a new vehicle, and a probability of 0.5 that you will purchase a used vehicle. There is no probability that you will go home with more than one vehicle. The probability that you purchase no vehicle at all is:

A. 0.9

B. 1.0

C. 0.1

D. 0.0

Solution

Probability that no vehicle is purchased

= 1 - probability of purchasing a used vehicle - probability of purchasing new vehicle

= 1 - 0.4 - 0.5

= 0.1

hence C is the correct choice
