A company publishes statistics concerning car quality. The initial quality score measures the number of problems per new car sold. For one year, Car A had 0.85 problems per car and car B had 1.28 problems per car. Let the random variable X be equal to the number of problems with a newly purchased model A car. Complete (a) through (c) below. a. If you purchased a model A car, what is the probability that the new car will have zero problems? The probability that the new model A car will have zero problems is. (Round to four decimal places as needed.) b. If you purchased a model A car, what is the probability that the new car will have two or fewer problems? The probability that a new model A car will have two or fewer problems is. (Round to four decimal places as needed.) c. Compare your answers in (a) and (b) to those for car B. Because Car B has a V mean rate of problems per car than Car A, the probability of a randomly selected Car B having zero problems and the probability of no more than two problems are both V than for Car A.

Transcribed Image Text:A company publishes statistics concerning car quality. The initial quality score measures the number of problems per new car sold. For one year, Car A had 0.85
problems per car and car B had 1.28 problems per car. Let the random variable X be equal to the number of problems with a newly purchased model A car. Complete
(a) through (c) below.
a. If you purchased a model A car, what is the probability that the new car will have zero problems?
The probability that the new model A car will have zero problems is
(Round to four decimal places as needed.)
b. If you purchased a model A car, what is the probability that the new car will have two or fewer problems?
The probability that a new model A car will have two or fewer problems is
(Round to four decimal places as needed.)
c. Compare your answers in (a) and (b) to those for car B.
Because Car B has a
mean rate of problems per car than Car A, the probability of a randomly selected Car B having zero problems and the probability of no
more than two problems are both
than for Car A.
