In a family with 9 children, excluding multiple births, what is the probability of having 9 girls? Assume that a girl is as likely as a boy at each birth. Let E be the event that the family "has 9 girls," where the sample space S is the set of all possible permutations of girls and boys for 9 children. Find the number of elements in event E, n(E), and the total number of outcomes in the sample space, n(S). n(E) = n(S) =| The probability of having 9 girls is (Type an integer or a simplified fraction.)
