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

 For a nurse it is quite normal because she knows the pattern of breathing of a small baby but for a primipara ( a lady who is giving birth for the first time ) it might not be  acceptable to understand the fact that a newly born baby has an irregular breathing  pattern switching in between fast and slow .
As she is a new mother she might not be aware of the fact that a baby breathes very fastly to compensate the amount of energy required to maintain the homeostasis of the baby.As the baby is in growing stage the amount of energy required is much more as compared to that of adults.
Hence , the nurse will not take any medical action as the baby is not sick but yes she will definitely tell the mother that it is normal in baby
