I'm having trouble working through the math of the problem below. I believe the problem as described is an ergodic process. I've written a simple simulation of the problem, that converges to 66.6...6% heads and 33.3...3% tails.
Question In the Coinland all the coins in the land were flipped and allowed to fall to the ground. (uniformly heads or tails, no bias coins or funny stuff etc).
As the people in Coinland walked around, if they encountered a coin on the ground they will do one of the following:
- Flip the coin it if is a tail
- Turn the coin over if it is a head
After a sufficiently large amount of time has passed, what percentage of the coins on the ground are heads?
I was hoping someone could provide some guidance/suggestions to possible avenues of investigations - if possible please don't provide an exact answer.
