Quizplus · Accepted Answer

The number of unique groups of teams that can make the playoffs is calculated using the combination formula, which is C(n, k) = n! / [k!(n-k)!], where n is the total number of teams (30) and k is the number of teams to choose (5). Thus, C(30, 5) = 30! / [5!(30-5)!] = 142,506.
