    Default Math question.......?

    Hello everybody!

    May I ask you a big favor?
    I need help.
    What I have is:
    A bag contains marbles of three different colors with at least three marbles of each color.
    Three marbles are randomly selected, without replacement. How many different color combinations are possible?

    I tried to use Combinatorial Calculator here:
    Combinatorial Calculator

    And I've got : 10

    Seems like it is the right answer, because textbook shows me the same..
    But I want to understand the way of solving it.
    Please show me step by step solution or the formula.

    Thanks in advance.

    Check the Wikipedia article on Combinations. Since your problem allows repetition, you will want to look in the "Number of combinations with repetition" section for the proper formula:
