$\textbf{Details and Assumptions}$

Note: The events described above in bullet points occur in addition to the removal of a chair every round and other rules stated below.

In musical chairs, players have to sit down on a chair by the end of the round. If a player isn't able to find a chair to sit down on by the end of the round, they are eliminated from the game. Every round, a chair is removed. The game ends when there is only one chair remaining, and the winner is the player that sits on the final chair. Each player has an equal chance of finding a chair.
