Hi there!
One way to find the solution is to list out all of the possible combinations- which, in most cases, will take a long time.
Another more effective way to find the possible combinations is to multiply the amount of each component together and find the product of all of the amounts of items combined.
In this case, you would multiply:
6 * 3 * 3 * 3 * 3
= 486.
So, there'd be 486 combinations.
Hope this helps!
