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?
um idon't know.
half of the people have girls already and have no boys. of the others 1/2 have one boy and on girl, 1/4 have 2 boys and 1 girl, 1/8 have 3 boys and one girl, 1/16 have 4 boys and one girl.
but what about the ones who are still having children?
