What are the chances the other is also a girl?

Assuming that the chance that the father will supply an X or a Y chromosome is equal (i/e, 50/50) then 50%. Why did you say 33%, Tuna?

I'm going to wait for a few more responses before explaining my position

Not that I think it would matter a whole lot, but do the kids have the same father? I read once during an anthropology class that if a couple has one child, subsequent children are more likely to be of the same gender as the first child. This theory wouldn't apply if the children had different fathers, because it's something to do with the process of meiosis in the man's body, and every man is different.

Same father: I'll say 66% more likely that the other child is also a girl. Not a poll option but I could add it for you if you want. (You already have 33% up there.)

Different father: 50% or less.

If the two kids are identical twins, then I guess the answer would be 100%.

If I know math; which I don't; then the answer is 42.
