This is a permutation problem because the order in which the officers are chosen matters. The formula for permutations is nPr = n! / (n-r)!, where n is the total number of items to choose from, r is the number of items to choose, and "!" denotes factorial, which means the product of all positive integers up to that number. Here, n=12 (the total members) and r=3 (the positions to fill). So, the calculation is 12P3 = 12! / (12-3)! = 12! / 9! = 12 x 11 x 10 = 1320.
