The tennis club is about to hold a tennis tourment among its members. There are 8 people signed up. If each player is going to play once against all the other players, how many matches there will be in this tourment?
选项
答案
28
解析
这道题本质上也是“握手问题”,可以利用上述方法求解。例如,从“参加比赛的人”的角度上看,每个选手都要和其他7个选手比赛1次,需比7次;一共有8位选手,因此共比8×7=56次。上述方法导致A与B的比赛和B与A的比赛被重复计算,因此应将上述结果除以2,即共需要举办56/2=28场。
