We discuss some particular cases of the following problem. Each of persons tosses
a coin. Those who get heads stay for the next round. Those who get tails are eliminated; however,
if all persons get tails in a round, they move to the next round (as if each of them had got a head).
The problem is to find the possibility that exactly one person is left after rounds. All coins are
considered identical but not necessarily fair.
