Quizplus · Accepted Answer

The number of ways to select 5 suspects out of 9 for a lineup is calculated using the combination formula, which is C(n, k) = n! / [k!(n-k)!], where n is the total number of items (9 suspects), and k is the number of items to choose (5 suspects). So, C(9, 5) = 9! / [5!(9-5)!] = 9! / (5!4!) = (9*8*7*6) / (4*3*2*1) = 126.
