More defective components: A lot of 934 components contains 387 that are defective. Two components are drawn at random and tested. Let A be the event that the first component drawn is defective, and let B be the event that the second component drawn is defective. Write your answer as a fraction or a decimal, rounded to four decimal places. (a) Find P(A). (b) Find P(BIA). (c) Find P(A and B). (d) Are A and B independent? Is it reasonable to treat A and B as though they were independent? Explain.
