From here you should be able to finish it, I think. The outcomes with two children are actually BB, BG, GB, and GG, where G stands for a girl, B for a boy, the first symbol gives the sex of the first child, and the second symbol gives the sex of the second child. Given that you are going to "select" exactly two children, find the probability that they are BOTH girls (it's a coin flip, so p = 50% = 0.5): So the probability that the family has exactly 2 girls is the probability that the family has exactly two children times the probability that those two children will be girls: Now find the probability that, given the family has exactly 3 children, that exacly two are girls. 1 0 obj
