Q: 

coding horror, the baby boy/girl question, probability

Hi, Just showed one of my flatmates this question from coding horror

He's just pointed out something obvious, what is the difference between boy/girl, girl/boy. And if there is a difference then surely there is a difference between girl younger girl older combinations etc.

Could be missing something but none of the comments seem to deal with this when other commentors raise the issue.

Any ideas / explanations?

+1  A: 

There is no difference, and that's why they are the two valid outcomes at the end, which leads to a conclusion of a 2/3 probability.

It seems that that particular question, for whatever reason, causes confusion between permutations and the likelihood of combinations
