The probability of having a child with albinism when both parents are carriers of the albinism gene is one in four.

1) If a couple has four children and both parents are carriers of the albinism gene, what is the probability that exactly one of their children is albino?

1i) Suppose a sample of 200 children are selected. Assume both parents are carriers of the albinism gene for all the selected children.

1II) What is the probability that more than 65 of these children are albino?
