The distribution of blood types in North America is as follows:
Type O: 44% Type A: 42%
Type B: 10% Type AB: 4%
A.) What is the probability that the first two people in the line up have the same type of blood?
P(both have same type) = 0.44^2 + 0.42^2 + 0.10^2 + 0.04^2
----------------------------------------------------------------------
B.) What is the probability that none of the first five people in the line have type AB blood??
P(none of 5) = 0.56^5 + 0.58^5 + 0.90^5 + 0.96^5
