or a particular pair of parents has probability 0.25 of having type O blood. Genetics says that children receive genes from each parent independently. Assuming these parents have 8 children, we can let X be the number of children with type O blood. The following table may (or may not) be useful: k 0 1 2 3 4 5 6 7 8 8 Ck 1 8 28 56 70 56 28 8 1 (a) What is the probability that exactly 3 children have blood type O? Round your answer to 3 decimal places. is (b) What is the probability that at least 6 children have blood type O? Round your answer to 3 decimal places. (c) What is the expected number of children with blood type O?
