Question 1147127
<br>
(1) Count the total number of games that each team plays; then, since that counts each game twice, divide by 2:<br>
(number of teams) times (number of opposing teams) times (number of times per season)
6*5*9 = 270
then divide by 2
270/2 = 135<br>
OR, to be a bit more sophisticated mathematically....<br>
(2) Determine the number of pairings and multiply by the number of times per season that each pairing occurs:<br>
(6 choose 2) times (number of times per season)
6C2 * 9 = 15*9 = 135<br>
