Combination, Permutation or Something Different?


I'm working on a project but I'm not sure if I'm dealing with a Combination, Permutation or something different.

I have 5 separate "select groups" - each "select group" has 10 items. The goal is to randomize the list so that I end up with a 5 pack bundle of different items - only 1 item from each of the 5 groups.

Number of sample points in set ( 50 )
Number of sample points in each permutation ( 5 )

Any help in pointing me in the right direction would be great!

Ask yourself what questions readers of your post might have, and then answer them.

Giving simplified examples with possible answers is a Dominant Strategy in the Game Theory sense and so may also help.

You know that what we call a Combination Lock is really a Permutation Lock, right?
The thing that is throwing me is the fact that there are 5 different groups to select data from - most of the examples I've seen for Combinations & Permutations don't give any examples or mention to "groups" - only straight lists. Also, there is the other issue that only 1 item from each group can form a "5 piece bundle".

Any thoughts?
