Question

In a certain population, 95% of the people have rh-positive blood. suppose that two people from this population get married. what is the probability that they are both rh-negative, thus making it inevitable that their children will be rh-negative? web assign answer

Answer 1

P(rh-positive) = 95% = 0.95

Therefore,
P(rh-negative) = 1-P(rh-positive) = 1-0.95 = 0.05

Then,
P(rh-negative) for both parents = 0.05*0.05 = 0.0025
