Question

In a baseball league consisting of 15 teams, each team plays each of the other teams three times. How many games will be​ played?

Answer 1

Answer:

  315

Step-by-step explanation:

Each of the 15 teams plays each of the other 14, for a total of 210 games. However, that count includes both A playing B and B playing A. Hence, if the teams meet 3 times, the total number of games will be 3/2 this amount:

  (15)(14)(3/2) = 315 . . . league games
