Quizplus · Accepted Answer

The number of different samples of size 3 that can be taken from a population of 5 elements 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 size of the sample. Here, n=5 and k=3, so C(5, 3) = 5! / [3!(5-3)!] = (5*4*3!) / (3!*2!) = 10.
