She learns that there are 151 cars matching that description A within a 30-mile radius of her home. Assume that those are the people who B will call her and that they are equally likely to call her Complete parts a c 33 31 64 through d. 11 43 Total 96 155 151 a) What is the probability that the first caller will own a car of make D? (Round to three decimal places as needed.) b)What is the probability that the first caller will own a car of make D that costs between $19,000 and $19,999? (Round to three decimal places as needed.) c) If the first call offers her a car of make D, what is the probability that it costs less than $20,000? (Round to three decimal places as needed.) d) Suppose she decides to ignore calls with cars whose cost is 2$20,000. What is the probability that the first call she takes will offer to sell her a car of make D? (Round to three decimal places as needed.)

Explanation / Answer

a) P(car of make D) = 24/151 = 0.159

b) P(car of make D that costs between $19000 and $19999 = 18/151 = 0.126

c) P(less than $20,000 | car of make D) = 19/24 = 0.792

d) P( car of make D if she ignores calls with cars whose cost is >20,000) = 19/96 = 0.198
