the probability of a male being color blind is 1/10
the probability of a female being color blind is 1/7
the probability of a person being selected being male is .5
the probability of a person being selected being female is .5
50% of the time you will select a male.
50% of the time you will select a female.
p(male) = .5
p(female) = .5
p(person) = .5 + .5 = 1
p(color blind male) = 1/10 = .1
p(color blind female) = 1/7 = .142857143
p(color blind person) = .5*.1 + .5*.142857143 = .121428571
