Suppose that you receive 10000 laptops, but 20% are defective. You pick two laptops at random, one after the other. Let A be the event that the first laptop is defective, and B that the second one is. Compute P(A), P(B), and P(An B). Does this mean that A and B are independent events or not? How much of a numerical difference does the assumption of independence make? Would it be different if there were only 10 laptops
