Question

You have 22 books in your library. Eight are romance novels, 4 are murder mysteries and the rest are science fiction. Only 15 books will fit on a book shelf. How many ways can you arrange the books?​

Answer 1

The books can be arranged in 170,544 ways

Explanation:

This is a combination question since we are arranging

We simply want to find the number of ways to select 15 books out of 22 for arrangement

Mathematically, that will be;

22 C 15 = 22!/(22-15)!15! = 170,544 ways
