2. -2 points DevoreStat9 2.E.074 My Notes Ask Your Teacher Suppose that the proportions of blood phenotypes in a particular population are as follows ABAB O 0.42 0.09 0.04 0.45 Assuming that the phenotypes of two randomly selected individuals are independent of one another, what is the probability that both phenotypes are O? (Enter your answer to four decimal places.) What is the probability that the phenotypes of two randomly selected individuals match? (Enter your answer to four decimal places.) Need Help?

Explanation / Answer

a) P(both phenotypes are O) = 0.45x0.45 = 0.2025

b) P(2 phenotypes match) = P(both A) + P(both B) + P(both AB) + P(both O)

= 0.422 + 0.092 + 0.042 + 0.452

= 0.3886
