Investigate!
Suppose you have some number of identical Rubik's cubes to distribute to your friends. Imagine you start with a single row of the cubes.
-
Find the number of different ways you can distribute the cubes provided:
You have 3 cubes to give to 2 people.
You have 4 cubes to give to 2 people.
You have 5 cubes to give to 2 people.
You have 3 cubes to give to 3 people.
You have 4 cubes to give to 3 people.
You have 5 cubes to give to 3 people.
Make a conjecture about how many different ways you could distribute 7 cubes to 4 people. Explain.
What if each person were required to get at least one cube? How would your answers change?
