A group of 100 people exhibited the following blood types:
A20 B24 AB10 O46
If one person is selected at random, what is the probability
A) The person has type AB blood?
My answer so far:P(type AB blood)=10/100=0.1 or 10%
B)the person has either type A or type O blood?
My answer so far: P(type A blood)=20 P(TYPE O blood)=46 =(20+46)/100=0.66
C) The person does not have type B blood?
I do not know where to start
D) The person has neither type B nor type O blood?
Thank you in advance for your help
