Quizplus · Accepted Answer

The number of ways to select 4 out of 10 tax returns is calculated using the combination formula, which is C(n, k) = n! / [k!(n-k)!], where n is the total number of items, k is the number of items to choose, and "!" denotes factorial. Here, n=10 and k=4, so C(10, 4) = 10! / [4!(10-4)!] = 10! / (4!6!) = (10*9*8*7) / (4*3*2*1) = 210.
