answer is 33% cause there's four different possibilities:
BG
GB
BB
GG
Because one of them is already a girl, that dismisses the possibility of BB, leaving:
BG
GB
GG
Since one of them is already a girl, 1/3 chance the other will also be a girl (GG)

You're assuming that each of those possibilities are equally likely, which they aren't. I don't know how much it affects the numbers, but statistically there are slightly more males conceived than females. Also, there are a certain percentage that are neither male nor female.
