Look who's in the house:
We have a full cast today with Brainers from around the world.
Here's a no brainer for you.
King Doty of the kingdom Polipoly loves his two daughters so much he wishes his whole kingdom were filled with girls. He makes a royal decree declaring
All child-bearing couples must continue to bear children until they have a daughter!
To avoid overpopulation, he makes an additional decree
All child-bearing couples will stop having children once they have a daughter!
The kingdom immediately began to follow his orders.
If the likelihood of each baby born being a girl is 50 percent then after twenty years what will be the expected ratio of girls to boys in Polipoly?
Shouldn't this be 1:1? Or am I oversimplifying it?
Yes.
It is a no brainer. No matter how much time goes on the birth ratio is the same.
This is a serious brainer from @mineopoly of Polipoly, 😁. I would say it be 1:1.
