From: jeffrey E. <[email protected]> Sent: Saturday, September 30, 2017 10:23 PM To: Barnaby Marsh Combinations in the Sample Space <http://math=orum.org/dr.math/faq/faq.prob.intro.htmliinote> In a two-child family, there are four and only four possible combinations o= children. 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. please note T=e information contained in this communication is confidential, may be a=torney-client privileged, may constitute inside information, and is int=nded only for the use of the addressee.
