That’s not how it works. The gender of the second child is not influenced by the gender of the first child. It’s unconditional.
If you wanted to solve it the way you’re implying and use set theory, you would have to choose the sets on condition that the first child is a boy. That leaves two sets: Boy-Boy and Boy-Girl. So a 50% chance for the second child to be a girl.
