4. What is the probability that at least 2 of the first 10 blood donors have Type B blood? 5. The blood drive has a total of 150 donors. Assuming that this is a typical number of donors for a school blood drive, what would be the mean and standard deviation of the number of blood donors who have Type B blood? 6. Surprised by the low number of Type B blood donors at the blood drive, the American Red Cross wonders if the 11% estimate was too high for your area. How many Type B blood donors would it take to convince you that the estimate might be too high? Justify your answer.
