a. What is the probability that he wil b. What is the probability that he will answer all questions incorrectly? C. What is the probability that he will answer at least one of the questions correctly? Compute this probability two ways. First, use the rule for mutually exclusive events and the probabilities shown in Table 2 of the Appendix. Then use the fact that P(r ≥ 1) = 1-P(r = 0). Compare the two results. Should they be equal? Are they equal? If not, how do you account for the difference?
