Question

There are 9 different colors of paint to choose from. Out of the 9 colors, how many ways can 4 different colors be chosen?

Answer 1

Your answer would be 126 ways hopefully this helps!

Answer 2

This is the concept of combination, the number of ways 4 different color can be chosen from 9 different colors will be:
9C4
=(9!)/(4!(9-4)!)
=362,880/(24×120)
=362,880/2880
=126
thus the number of ways is 126 ways
