Quizplus · Accepted Answer

The number of ways to choose 2 pieces of candy from 12 is calculated using the combination formula, which is C(n, k) = n! / [k!(n-k)!], where n is the total number of items, and k is the number of items to choose. Here, n=12 and k=2, so C(12, 2) = 12! / [2!(12-2)!] = 12! / (2!10!) = (12*11) / (2*1) = 66.
