    Question

    Genetics teaches that children inherit genes from their parents. If both parents carry the genes O and A for blood type, each child has a chance of 0.25 to inherit two O genes to become blood type O. The number of children with blood type O among five offspring of these parents is the number of successes X in five independent attempts. Suppose that chance variable X the number of successes with blood type O, so X has the values as 0, 1, TRUE. , 5 and the Binomial (5, 0.25)-distribution. Then what is the probability that X = 2?
