#### Abstract

In many sports games, we would use a coin or the game of rock-paper-scissors to decide which side will begin rst. We consider the game of rock-paper-scissors when two teams are composed of two individuals respectively. There are many methods to choose one team of the two. We consider all 3 cases when all 4 individuals participate simultaneously or one by one. According to the methods of the game rules we nd the means and variances of the number of games respectively.
