To find : Probability that the person owns a Chevy, given that the truck has four-wheel drive

Answer to Problem T5.2SPT
c. 32/125
Explanation of Solution
Given information : Table showing brand of truck used by 125 truck owners and whether or not the truck has four-wheel drive.
Total number of truck owners = 125
Number of truck owners who own a Chevy, given that the truck has four-wheel drive = 32
Therefore,
Probability that the person owns a Chevy, given that the truck has four-wheel drive =
(Number of truck owners who own a Chevy, given that the truck has four-wheel drive)/ (Total number of truck owners) = 32/125
Option c. is correct
