Question:
Suppose that a couple has four children. Assume that all 16 outcomes in the sample space are equally likely.
a. List the sample space of all possible outcomes for the sexes of these four children. (For example, three of the possible outcomes are B1B2B3B4, B1G2B3G4, and B1B2G3G4, where Bi means that the ith child is a boy and Gi means that the ith child is a girl.)
b. Determine the probability that all four children are of the same sex.
c. Which is more likely—that the couple will have 2 children of each sex or a 3–1 breakdown? Justify your answer.
