   Mutually exclusive and non-mutually exclusive events can also be applied to real-life scenarios.

    

   In the National Hockey League, there are a number of ways for teams to earn points during the regular season. A regulation game is 60 minutes. A team that wins in regulation time gets 2 points; a team gets 0 points if it loses in regulation time.

    

   If a game ends in a tie after regulation time, then there is a five-minute overtime period. If the game is still tied after overtime, a shootout follows. In a shootout, individual players take turns trying to score to win the game. This shootout continues until one team wins. In overtime or a shootout, the winning team gets 2 points and the losing team gets 1 point.

    

   Using this information, answer the following questions:
   1. Describe events in regulation time that are mutually exclusive. Answer
   2. Describe events in overtime or in a shootout that are non-mutually exclusive. Answer
   3. Describe events in overtime or in a shootout that are complementary. Answer
