Quality control A consumer organization estimates that 29% of new cars have a cosmetic defect, such as a scratch or a dent, when they are delivered to car dealers. This same organization believes that 7% have a functional defect—something that does not work properly—and that 2% of new cars have both kinds of problems.

1. If you buy a new car, what’s the probability that it has some kind of defect?

2. What’s the probability it has a cosmetic defect but no functional defect?

3. If you notice a dent on a new car, what’s the probability it has a functional defect?

4. Are the two kinds of defects disjoint events? Explain.

5. Do you think the two kinds of defects are independent events? Explain.
