There are 5
Step-by-step explanation 5!= 5*4*3*2*1 = 120 different ways
There are 24 different ways to hang 4 paintings on a wall
For any basic occurrence of any item we use the factorial of that number. In other words factorial is the fact that there are n! ways to arrange n distinct objects into a sequence.
Since we are given with 4 items so their occurrence can be written as 4! which equals 4x3x2x1 = 24
