Question

People with type o-negative blood are referred to as universal donors, although if you give type o-negative blood to any patient you run the risk of a transfusion reaction due to certain antibodies present in the blood. however, any patient can receive a transfusion of o-negative red blood cells. only 8.7% of the american population have o-negative blood. if 8 people appear at random to give blood, what is the probability that at least one of them is a universal donor? (use 4 decimal places.)

Answer 1

There's an approximate 0.696% chance that one of those donors is a universal donor.
