Question

The quality of new Ferrari cars is assessed by sending each new car through a certifier who examines every part of the car’s interior and exterior for defects and counts the number of defects. The number of defects averages 0.1 per car.

Note: Make sure to specify the random variables and their distributions. Use the appropriate cumulative distribution tables to compute the probabilities.

(a) Find the probability the next inspected car will have more than 1 defects. (5 pts.)

(b) Find the probability that at least five of the next ten cars inspected will have no defects. (15 pts)
