    There are programs on calculators that will do this for you, but if you want an actual lesson the calculator can't teach you.

    OK well first do you understand that this is a combination equation and not a permutation.

    Oops Mistake Read again.

    But a combination is when the order does not matter.
    AB = BA.


    Edit: The only bad thing is that the question doesn't state whether order matters or not.

    So if the order did not matter than there would be only one way to take the marbles out of the bag.

    I have to get back to my own homework, if I had the time I would explain it.
