Congratulations! It's a child!
All students with exactly 1 sibling, please stand.
If your sibling is of opposite sex, stay standing. Otherwise, sit down.
Do you predict half of them will stay standing? More than half? Less than half?
Fun: Ask all your students with exactly 1 sibling to stand. Ask each if their sibling is of opposite sex. If you're right they stay standing
