If I have 5 different types of trees and want to plant them in groups of three, how many different combinations of groups can I make.
I worked this out and came out with 30.
Am I right?
Thanks for your help
You are using the word "combinations" so it would be
C(5,3) or 10 of them
suppose you have A, B, C, D, E kind of trees
