Abstract

In many sports games, we would use a coin or the game of scissors-paper-stone to decide which side will begin first. We consider the game of scissors-paper-stone when two teams are composed of N respectively. We continue the game of scissors-paper-stone until the winner of the two team is decided. Using sample spaces and enumerating the elements we calculated the mean number of the game when N = 1, N = 2 and N = 3. In case of N = 1 and N = 2, we simulate the game and find the mean and variance when the repetition number n = 20; 30; 50; 100; 150; 200.

각각 N명으로 구성된 두 팀이 경기를 하기 전에 공격과 수비를 정해야하는 경우가 발생한다. 경우의 수를 통하여 각 팀이 N = 1, N = 2 그리고 N = 3인 경기의 경우 모든 사람들이 참가하여 가위바위보를 통하여 승부가 결정될 때까지의 평균 게임수를 계산하였다. 실제로 모의실험을 통하여 평균 게임수를 구하여 이를 비교하였다.
