1. A Canadian dealer recently identified two serious manufacturing defects in some of his car models. A randomly selected car is estimated to have a 3 % chance of having the first defect, a 5% chance of having the second, and a 2% chance of having both. What is the probability that (a) it will have the first defect knowing that it does not have the second? (b) it will have at least one of these defects but not both? 2. Suppose that this dealer has 45 cars, 25 of which are compact cars. What is the probability that out of the next 10 sales, 8 will be compact cars? Is a probabilistic approximation possible under these assumptions
