Question

There are four basic blood groups: o, a, b, and ab. Ordinarily, anyone can receive the blood of a donor from their own group. Also, anyone can receive the blood of a donor from the o group, and any of the four types can be used by a recipient from the ab group. All other possibilities are undesirable. An experiment consists of drawing a sample of blood and determining its type for each of the next two donors who enter a blood bank.



a. Find the probability that the second donor can receive blood from the first donor.



b. Find the probability that each donor can receive blood from the other.



c. Find the probability that neither can receive blood from the other.
