Question

A textbook search committee is considering 12 books for possible adoption the committee has decided to select 8 of the 12 for further consideration and how many ways can it do so

Answer 1

495 ways

Explanation:

We solve this above question busing the combination formula

C(n,r) = nCr

= n!/(n - r)! × r!

We are told in the question that:

A textbook search committee is considering 12 books for possible adoption the committee has decided to select 8 of the 12 for further consideration

C(12, 8)

n = 12

r = 8

12C8 = 12!/8! × (12 - 8)!

= 12!/8! × 4!

= 495 ways
