You live in a society where female children are preferred over male children. By law, couples have to conceive children until they produce a female offspring. If their first child is male, they are allowed to have additional children until a female is born. Once a female is born, they are allowed no additional children.
What is the average ratio of females to males in this society?
The ratio will be 50/50.
