What you are looking for is called "Combinations" - and there is a lot about them out there, some of which may be useful to you. Google can help a lot here in working out the algorithm.

But...it's your homework, and it's important that you do it yourself: it is set for a reason. It is there so that you think about what you have been told, and try to understand it. It is also there so that your tutor can identify areas where you are weak, and focus more attention on remedial action.

Try it yourself, you may find it is not as difficult as you think!

If you meet a specific problem, then please ask about that and we will do our best to help. But it is very important that you try for yourself.
