For this reason, donors with this blood type are crucial to blood banks. Unfortunately, this blood type is fairly rare; according to the Red Cross, only 7% of U.S. residents have type o negative blood. Assume that a blood bank has recruited 20 donors, Round your answers to four decimal places. Part 1 of 3 (a) What is the probability that three or more of them have type o negative blood? The probability that three or more of them have type o negative blood is 0.1610 Alternate Answer: The probability that three or more of them have type o negative blood is 0.161 Part: 1/3 Part 2 of 3 (b) What is the probability that fewer than five of them have type o negative blood? The probability that fewer than five of them have type o negative blood is X 5
(a) What is the probability that three or more of them have type o negative blood? (b) What is the probability that fewer than five of them have type o negative blood? (c) Using a cutoff of 0.05, would it be unusual if none of the donors had type o negative blood?
