10.6871 Points] DETAILS PREVIOUS ANSWERS BBBASICSTAT8 6.2.016.MI.S. Richard has just been given a 4-question multiple-choice quiz in his history class. Each question has five answers, of which only one is correct. Since Richard has not attended class recently, know any of the answers. Assuming that Richard guesses on all four questions, find the indicated probabilities. (Round your answers to three decimal places.) LA USE SALT (a) What is the probability that he will answer all questions correctly? 0.0016 (b) What is the probability that he will answer all questions incorrectly? 0.4096 (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 in the binomial probability distribution table. 0.5904 Then use the fact that P(r 2 1) = 1 - P(r = 0). X Compare the two results. Should they be equal? Are they equal? If not, how do you account for the difference? They should be equal, but may not be due to table error. They should not be equal, but are equal. They should be equal, but differ substantially. They should be equal, but may differ slightly due to rounding error. (d) What is the probability that Richard will answer at least half the questions correctly? Enter a number. Need Help? Read It Master It Viewing Saved Work Revert to Last Response Submit
