People with blood type O- are sometimes referred to universal donors as their blood can be used for all recipients. About 9% of the Australian population have blood type 0-. Suppose blood donors have the same distribution of blood types as the Australian population. In any 10 donors chosen at random, what is the probability that exactly 3 will have O- blood? In any 10 donors chosen at random, what is the probability that between 1 and 4 inclusive will...
