Combination Problem, I think!
I have an interview panel made of:

1 Manager
1 Human Resource person
1 Supervisor

I have 5 managers to choose from
I have 6 Human Resource people to choose from
I have 7 supervisors to choose from

How many combinations could make up the interview panel.

Since order does not matter, I know it is not a permutation problem. How do I set up this problems???

Thanks,

$5\cdot 6\cdot 7$ simple multiplication.

What if we change it up a bit:

Need 1 manager, 2 human resource persons, and 1 supervisor. Does this matter to the problem???
