We will label boys B and girls G; in each case the first letter represents the oldest child: {BB, BG, GB, GG} When we know that one child is a boy, there cannot be two girls, so the sam=le space shrinks to: {BB, BG, GB} Two of the possibilities in this new sample space include girls: {BG, GB} and since there are two combinations out of three that include girls, the probability that the second child is a girl is 2/3. =lease note The information contained in this communication is c=nfidential, may be attorney-client privileged, may constitute inside in=ormation, and is intended only for the use of the addressee.
