Yeah I second that...the question is worded somewhat ambiguously. I assumed u were asking what the chances are that the last child is a boy, not "what are the chances all three children are boys". You already know the other two children are boys so there are only the two options of B/B/B or B/B/G.

EDIT: whoops nevermind...replied too early, and didn't realize there was another page of posts lol.
