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...

Tom and Jane participate in a Red Cross blood drive. Both are first-time donors. As part of the screening process, their blood is typed. Tom is Group A+. Jane is Group AB+. EMTs bring two accident victims into the emergency room at the hospital. One victim is bleeding from a head wound and needs a transfusion of blood cells to replace what she has lost. She is Group AB+. From this information, you conclude that Jane’s blood cells can be...
