The blood type o negative is called the "universal donor" type because it is the only blood type that may safely be transfused into any person. therefore, when someone needs a transfusion in an emergency and their blood type cannot be determined, they are given type o negative blood. 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 percentage of u. s. residents have type o negative blood. assume that a blood bank has recruited 20 unrelated donors. (state calculator entry and give 4 decimal places) what is the probability that fewer than three of them will have type o negative blood? what is the probability that more than 4 of them have type o negative blood? find the probability that none of the donors had type o negative blood. would this be unusual? explain. what is the mean of the number of donors who have type o negative blood for a group this size? what is the standard deviation of the number of donors who have type o negative blood for a group this size?
