The proportions of blood phenotypes in the U.S. population are as follows:
A.40 B.11 AB.04 O.45
Assuming that the phenotypes of two randomly selected individuals are independent of one another,
A. what is the probability that both phenotypes are O?
Ans: P(2 O's) = 0.45^2 = 0.2025
---------------------------------------
B. What is the probability that the phenotypes of two randomly selected individuals match
Ans 0.4^2+0.11^2 + 0.04^2 + 0.45^2 = 0.3762
