The manager at the local auto shop has found that the probability that a car brought into the shop requires an oil change is 0.83, the probability that a car brought into the shop requires brake repair is 0.17, and the probability that a car requires both an oil change and brake repair is 0.15. For a car brought into the shop, determine the probability that the car will require an oil change or brake repair.

0.85

Step-by-step explanation:

Given two events A and B, the probability that either A or B occurs is given by:

where

the probability that A occurs

is the probability that B occurs

is the probability that both A and B occur at the  same time

In this problem, we know the following facts:

is the probability that the car requires an oil change

is the probability that the car requires a brake repair

is the probability that the car requires both an oil change and brake repair

Therefore, the probability that either o (car requiring oil change) or b (car requiring brake repait) occur is:

a) t'(-3, 6) and v'(0, 3)
