13.13 and 13.14
In problems 13.13 and 13.14, it asks the probability given that one is a girl. Does it mean that there is only one girl or there is at least one girl?

I think it is saying that at least one is a girl since there can be 2 girls and 1 boy or 1 girl and 2 boys, but we know that there cannot be 3 boys because one of the children is a girl.
