At a certain car dealership, 20% of customers who bought a new vehicle bought an SUV, and 3% of them bought a black SUV. Given that a customer bought an SUV, what is the probability that it was black?

0.15 is the probability that  that a black SUV is bought, given that a customer bought an SUV.

Step-by-step explanation:

We are given the following in the question:

A: customers who bought a new vehicle bought an SUV

B: customers who bought a new vehicle bought an black SUV

We have to find the probability that a black SUV is bought, given that a customer bought an SUV.

We have to evaluate:

Thus, 0.15 is the probability that  that a black SUV is bought, given that a customer bought an SUV.

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
