Canadian Blood Services is a not-for-profit organization that collects nearly one million units of blood per year. About 6% of people have O-negative blood. They are called universal donors because O-negative blood can be given to anyone, regardless of the recipient's blood type. Suppose that 27 blood donors arrive at one of this organization's donation centers.

A) What is the probability that there are at least 2 donors?

B) What is the probability that there are less than three universal donors?

C) What is the probability that there are exactly three universal donors?
