Suppose that three players $($A$,$ B$,$ and C$)$ are playing a game. These three players are choosing

which of them has to mow the lawn. Player A and Player B will vote for who has to mow the lawn.

The game goes like this: Player A and Player B both play simultaneously. Player A gets to choose

a Player, so Player A$,$ Player B$,$ or Player C$.$ Player B also gets to choose a Player, so Player A$,$

Player B$,$ or Player C$.$ Player C then gets to observe the choices that Player A and Player B chose,

and then gets to choose a Player, so Player A$,$ Player B$,$ or Player C$.$
