[-/3.54 Points] Consider a binomial experiment with n = 7 trials where the probability of success on a single trial is p = 0.10. (Round your answers to three decimal places.) LO USE SALT (a) Find P(r = 0). (b) Find P(r > 1) by using the complement rule. 4. [-/3.54 Points] DETAILS BBUNDERSTAT12 5.2.015. MY NOTES ASK YOUR TEACHER A fair quarter is flipped three times. For each of the following probabilities, use the formula for the binomial distribution and a calculator to compute the requested probability. Next, look up the probability in the binomial probability distribution table. (Enter your answers to three decimal places.) (a) Find the probability of getting exactly three heads. (b) Find the probability of getting exactly two heads. (c) Find the probability of getting two or more heads. (d) Find the probability of getting exactly three tails. 5. [-/3.54 Points] DETAILS BBUNDERSTAT12 5.2.016.MI.S. MY NOTES ASK YOUR TEACHER 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, he doesn't 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? (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 the binomial probability distribution table. Then use the fact that P(r 2 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? O They should be equal, but differ substantially. O They should not be equal, but are equal. They should be equal, but may differ slightly due to rounding error. They should be equal, but may not be due to table error. (d) What is the probability that Richard will answer at least half the questions correctly
