part 4 please

Car inspection: Of all the registered automobiles in Colorado, 3% fail the state emissions test. Twelve 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 three of them fail the test. The probability that exactly three of them fail the test is | 0.0173 X Part 2 of 4 (b) Find the probability that fewer than three of them fail the test. The probability that fewer than three of them fail the test is |0.9804 5 Part 3 of 4 (c) Find the probability that more than two of them fail the test. The probability that more than two of them fail the test is 0.3125 X Part: 3 / 4 Part 4 of 4 (d) Would it be unusual for none of them to fail the test? Use a cutoff of 0.05. It would not |be unusual for none of them to fail the test since the probability is X 5 Continue
