Peter guesses on all 10 questions of a multiple-choice quiz. each question has 4 answer choices, and peter needs to get at least 7 questions correct to pass. here are some probabilities computed using the binomial formula: p(getting exactly 7 correct) = 0.0031 p(getting exactly 8 correct) = 0.000386 p(getting exactly 9 correct) = 2.86 × 10−5 p(getting exactly 10 correct) = 9.54 × 10−7 using the information on the left, combine the individual probabilities to compute the probability that peter will pass the quiz.
