Answer :
Total number of games for 9 teams so that each team will play 12 games in the baseball league will be 432
Total number of teams in the baseball league is 9
Total number of games that each team will play is 12
Since, each team will have option of 8 teams to play with since no team can play with itself
Therefore, number of games that each team will play after playing 12 games will be 8 x 12 = 96
Since there are 9 teams, therefore total number of games that two teams will play = 96 x 9 = 864
Now, as it takes two teams to play a game therefore the required number of games for the 9 teams = 864/2 = 432
