The distribution of blood types for a population are:

40% typeA

9% type B

49% type O

2% type AB

Suppose that the blood types are independent and that both the husband and the wife follow this distribution of blood type.

a) If the wife has type B, what is the probability that the husband has type B?

b) What is the prob that both husband and wife have type B?

c) What is the prob that husband and wife have same blood type?

d) An individual with type B blood can safely receive transfusions only form people with type B or O. What is the probability that the husband of a women with type B blood is an acceptable donor for her?
