Question

Quizplus · Accepted Answer

The probability of an SUV requiring only a tune-up can be found by subtracting the probability of both a tune-up and a brake job from the probability of only a tune-up.
P(tune-up but not brake job) = P(tune-up) - P(tune-up and brake job) = 0.6 - 0.02 = 0.58. Therefore, the best choice is B.
