Question

Griffin, Craig, and Tony are playing rho-sham-bo, otherwise known as rock-paper-scissors.It is a game for two players.The game has gotten boring because Griffin always chooses rock, Craig always chooses scissors, and Tony always chooses paper.Thus, when Griffin plays against Craig, Griffin wins (rock smashes scissors).When Craig plays Tony, Craig wins (scissors cut paper), And Tony beats Griffin when they play (paper covers rock).Suddenly, two of the participants exchange preferences, while the third participant remains the same.If Craig now plays Griffin, who wins?

Explanation / Answer

Initially,

Case 1: Griffin keeps the rock. Craig and Tony interchange

So, when Griffin plays Craig, Craig wins (paper covers rock)

Case 2: Craig keeps the scissors,Griffin and Tony exchange.

So when Griffin plays Craig, Craig wins again (scissors cut paper).

Case 3: Tony keeps paper, Griffin and Craig exchange.

So when Griffin plays Craig, Craig will win (rock smashes scissors).

We see in all 3 cases when Griffin plays Craig, Craig always wins.
