    So let's start by naming our people, let's say Robert, Sasha, Tyler, Bryan, and Katie. Now start listing all the ways that they can go in a organized way.

    Robert, Sasha, Tyler

    Robert, Sasha, Bryan

    Robert, Sasha, Katie

    Robert, Tyler, Bryan

    Robert, Tyler, Katie

    Robert, Bryan, Katie

    Sasha, Tyler, Bryan

    Sasha, Tyler, Katie

    Tyler, Bryan, Katie

    And that is it, 9, without repeating the same groups
