Family C has eight children: three girls, one boy, and then four more girls. Family D also has eight children: two girls, one boy, one girl, three boys, and then a girl. Which type of family is more probable?
Suppose that the probability that a baby is a boy is 0.5 and that a baby is a girl is also 0.5. Find the probabilities of each of the following families. Assume that the sexes of babies are independent of each other.
