Text: When all teams in a league play each other twice, a total of N games are played, where N = n^(2). There are 4 teams.
Added by Matthew G.
Step 1
For n teams the number of distinct pairs is n(n−1)/2; since each pair plays twice, N = 2·[n(n−1)/2] = n(n−1). (The given N = n^2 is not correct.) Show more…
