Geometric/Binomial Probabilities Part 1: The American Red Cross says that about 1 190 of the US. population has Type B blood. A blood drive is being held at your school. 1. How many blood donors should the American Red Cross expect to collect from until it gets a donor with Type B blood:? 2. What is the probability that the tenth blood donor is the first donor with Type B blood? 3. What is the probability that exactly 2 of the first 20 blood donors have Type B blood? 4. What is the probability that at least 2 of the first 10 blood donors has Type B blood? 5. The blood drive has a total of 150 donors. Assuming this is a typical number of donors for a school blood drive, what would be the mean and standard deviation of the number of donors who have Type B blood?
