One of my co-interns gave me this riddle a few years back:
So there's a family with two kids.
One of the kids is a girl. What is the probability that the other kid is girl?
(It's not 1/2)

one-third.
ReplyDeletepossible combos of birthing two kids:
BB,BG,GB,GG.
omit BB since one kid has to be a girl.
