Question

5. Suppose a family contains two children of different ages, and we are interested in the gender of these children. Let F denote that a child is female and M that the child is male and let a pair such as FM denote that the older child is female and the younger is male. There are four points in the set S of possible observations: S = {FF, FM, MF, MM}. Let A denote the subset of possibilities containing no males; B, the subset containing two males; and C, the subset containing at least one male. List the elements of A ? B ? ?. a. {FF, MM} b. {FF, MM, FF} c. {FF} d. {FF, FM, MF, MM}.
