Howl posted...I did read it, and it's incorrect No, not all those outcomes are possible as will be determined by the very first coin flip. 3 of the possibilities are eliminated instantly and therefore should not be calculated at all. There's never going to be an instance where all 7 possibilities are possible therefore they should not all be calculated in that way. --- woof ... Copied to Clipboard!

There's never going to be an instance where all 7 possibilities are possible therefore they should not all be calculated in that way. Again, you're assuming that one specific child is the girl. In this case, the first child. I actually covered this scenario and the related 25% probability in my post. ... Copied to Clipboard!

P(all 3 girls | at least one girl) = P(all 3 girls & at least one girl)/P(at least one girl) = P(all 3 girls)/P(at least one girl) = (1/8) / (7/8) = 1/7
