Car inspection: Of all the registered automobiles in a city, 10% fail the emissions test. Fifteen automobiles are selected at random to undergo an emissions test. Round the answers to at least four decimal places. Part 1 of 4 (a) Find the probability that exactly four of them fail the test. The probability that exactly four of them fail the test is 1.2221 X 5 Part 2 of 4 (b) Find the probability that fewer than four of them fail the test. The probability that fewer than four of them fail the test is 4.0331 X 5(c) Find the probability that more than three of them fail the test. The probability that more than three of them fail the test is (:11 Would it be unusual for fewer than three of them to fail the test? It m be unusual for fewer than three of them to fail the test since the probability is
