Quizplus · Accepted Answer

The number of different subsets of size 5 from a set of 9 elements can be calculated using the combination formula, which is C(n, k) = n! / [k!(n-k)!], where n is the total number of elements and k is the size of the subset. Here, n=9 and k=5, so C(9, 5) = 9! / [5!(9-5)!] = 9! / (5!4!) = (9*8*7*6) / (4*3*2*1) = 126.
