Quizplus · Accepted Answer

The number of different groups of five that can be formed from twelve accounts is calculated using the combination formula, which is C(n, k) = n! / [k!(n - k)!], where n is the total number of items, k is the number of items to choose, and "!" denotes factorial. Here, n = 12 and k = 5, so C(12, 5) = 12! / [5!(12 - 5)!] = 12! / (5!7!) = 792.
