The statement of the question tells us that 45% of the customers getting an oil change will have their car tires rotated. Therefore:
probability of both = 0.7 x 0.45
= 0.315
= 31.5%
probability of both = 0.7 x 0.45
= 0.315
= 31.5%
Answer:
64.3%
Step-by-step explanation:
You are finding a conditional probability. You divide the second percent by the first percent.
P(B | A) = [P(A and B)] / P(A)
P(A) = 0.7
P(A and B) = 0.45
= 0.45 / 0.7
= 0.643
= 64.3%
