The distribution of blood types is given by the following table.

a. Find the probability that the person has Type B blood and his partner has Type O blood.

b. Given that the person has Type A blood, what is the probabilty that his partner has type AB blood?

Solution

a) The probability that the person has type B blood and partner type O blood

= Product of probabilities as two events are independent

= 0.10(0.45)

=0.045

---------------------------------------------------------------

b) Prob (his partner has type AB blood/the person has type A blood)

= Prob (His partner has type AB blood) (as independent events)

= 0.05
