probability

Question

The percentage of the general population that has each blood type is shown in the following table.  Determine the probability distribution associated with these data.

 

Blood Type -      A         B        AB        O

Population(%) - 41        12        3         44

Answer 1

A probability distribution simply lists each possible outcome and its probability. For these blood types, each type is associated with a percent of the population. From there, it's easy to find probability. For Type A, for example, the probability is 41/100 = 0.41. So:

 

P(Type A) = 0.41

P(Type B) = 0.12

P(Type AB) = 0.03

P(Type O) = 0.44
