Question

At an auto care shop, 70% of customers get an oil change for their car. Only 45% of customers get an oil change for their car and get their car tires rotated. What is the probability that a customer who gets an oil change for their car also gets their car tires rotated? Round your answer to the nearest tenth of a percent.

Answer 1

The probability that a customer who gets an oil change for their car also gets their car tires rotated is 0.45.

Step-by-step explanation:

To find the probability that a customer who gets an oil change for their car also gets their car tires rotated, we need to divide the number of customers who get both services by the number of customers who get an oil change. Let's say we have 100 customers. According to the given information, 70% of customers get an oil change, which is 70 customers. Out of these 70 customers, only 45% also get their car tires rotated, which is 31.5 customers. Therefore, the probability is 31.5/70 = 0.45 (rounded to the nearest tenth).
