A simplified model of the human blood-type system has four blood types: a, b,ab and o. thereare two antigens, anti-a and anti-b.
Kay [80]
First calculate the probability of type AB, which is the remainder after subtracting types A, B and O.

P(AB) = 1-(0.34+0.12+0.5) = 1-0.96 = 0.04

Anti-b will react with types B and AB, so 
P(reaction) = P(B)+P(AB) = 0.12 +  0.04 = 0.16

Answer: For this person, the probability of reaction with anti-b is 0.16
