A batch of 500 semiconductor devices contains 25 that are defective. Two are selected, at random, without replacement from the batch. (a) What is the probability that the second one selected is defective given that the first one was defective? (b) What is the probability that both are defective? (c) What is the probability that both are not defect? If three devices are selected at random without replacement from the batch; (d) What is the probability that the third one selected is defective given that the first and second ones selected were defective? (e) What is the probability that the third one selected is defective given that the first one selected was defective and the second one selected was not defect? (f) What is the probability that all three devices are defective?
