I misstated the original problem. If you have an endless supply of posterboard in 6 different colors, in how many ways can you package 5 posterboards ?

If the first answer is not what you meant, then I assume that a package could contain say three yellow, one green and one red.
If that is the case this is a multi-selection problem.
We can select items from different kinds in ways.
