In one nation, having a daughter is traditionally prefferable to having a son. Therefore, a couple will continue to have children until a daughter is born. Once they have a daughter, they will stop. (Assume that it is possible for a couple to have an unlimited number of children)

If the chance of a boy or a girl being born is equal, what would be the ratio boys to girls in this country?

This is one of the easier ones on the net. No mathematical computations necessary, if the chances are equal and we are on a 100% scale. 50% chance it'll be a boy and 50% chance it will be a girl. The ratio is, therefore, 1 to 1.
