Answer 1

Answer:

0.05 is the probability that a customer purchases a black SUV.

Step-by-step explanation:

The following information is missing in the question:

"At a certain car dealership, the probability that a customer purchases an SUV is 0.20. Given that a customer purchases an SUV, the probability that it is black is 0.25."

We are given the following in the question:

Probability a customer buys a SUV = 0.20

$P(S) = 0.20$

Probability that the SUV is black, given customer purchases a SUV = 0.25

$P(B|S) = 0.25$

We have to find the probability that a customer purchases a black SUV.

Thus, we have to evaluate:

$P(B\cap S)$

Formula for conditional probability:

$P(B|S) = \dfrac{P(B\cap S)}{P(S)}\\\\P(B\cap S) = P(B|S)\times P(S) = 0.25\times 0.20 = 0.05$

0.05 is the probability that a customer purchases a black SUV.
