Quizplus · Accepted Answer

The number of ways to select 4 books out of 12 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 = 12 and k = 4, so C(12, 4) = 12! / [4!(12 - 4)!] = 12! / (4!8!) = 495.
