Question

Human blood is typed as O, A, B, or AB and also as Rh-positive or Rh-negative. ABO type and Rh-factor type are independent because they are governed by different genes. In the American population, 84% of people are Rh-positive. Use the information about ABO type in the table to give the probability distribution of blood type (ABO and Rh) for a randomly chosen person.

Answer 7
Answer 8 Blood type U.S. probability AB 0.42 0.11 2 0.44

Explanation / Answer

P(AB)=1-(0.42+0.11+0.44)=0.03

a)P(O+)=P(O)*P(Rh+)=0.44*0.84=0.3696

b)P(O-)=P(O)*P(Rh-)=0.44*0.16=0.0704

c) P(A+)=P(A)*P(Rh+)=0.42*0.84=0.3528

d) P(A-)=P(A)*P(Rh-)=0.42*0.16=0.0672
