Question

Carla is going to arrange her 4 books on a shelf: Algebra, Trigonometry, Geometry and Calculus. How many different possible arrangements can she make

Answer 1

Arranging of books is an illustration of permutation and combination

There are 24 different possible arrangements she can make

How to calculate the number of arrangement

The number of books is given as:

n = 4

Take the factorial of both sides

n! = 4!

Evaluate

n! = 4 * 3 * 2 * 1

n! = 24

Hence, there are 24 different possible arrangements she can make
