a group of 100 people have the blood types A20 B24 AB10 O46.
If 1 person is selected at random
what is the probability
that the person has type AB blood = 10/100 = 1/10
----------
the person has either type A of type O blood = (20/100)+(46/100) = 33/50
----------
: the person does not have type B blood = 1-(24/100) = 76/100 = 19/25
---------
: the person has neither type B nor type O blood = (24/100)(46/100)=0.1104
