Quizplus · Accepted Answer

The number of different samples of size 2 that can be obtained from a population of size 5 is calculated using the combination formula, which is C(n, k) = n! / [k!(n-k)!], where n is the population size and k is the sample size. Here, n=5 and k=2, so C(5, 2) = 5! / [2!(5-2)!] = 10.
