SUPP 2.4
The blood type distribution can differ from country to country. For example, consider the blood type distribution of Ireland. P(A) = 0.35, P(B)= 0.10, P(AB)= 0.03, P(O)=0.52. Find the probability that:
a. Two randomly chosen people from this population are both type B
b. In two randomly chosen people from this population, neither is type B
c. Two randomly chosen people from this population have same blood type.
d. In two randomly chosen people from this population, at least one is type B.
e. In five randomly chosen people from this population, at least one is type O.
a) The probability that two randomly chosen people from this population are both type B
b) The probability that in two randomly chosen people from this population, neither is type B
c) The probability that two randomly chosen people from this population have same blood type
d) The probability that in two randomly chosen people from this population, at least one is type B
= 1 - P( none of the selected two people is type B)
e) The probability that in five randomly chosen people from this population, at least one is type O
