Define Probability

Probability is the likelihood that something will occur. When we don't know how an event will turn out, we can discuss the likelihood or likelihood of several outcomes.Statistics is the study of events that follow a probability distribution.

Given,

Blood type 'o' = 0.30

Blood type 'a' = ?

Blood type 'b' = 0.10

Blood type 'ab' = 0.05

find, the probability of the blood type 'a'

Probability(person having blood type a) = 1 - 0.30 - 0.10 - 0.05

                                                                  = 0.55

Hence, The probability of the person having blood type a is 0.55.
