Homework Help: Tree Diagram help

  1. Nov 9, 2009 #1
    1. The problem statement, all variables and given/known data
    Draw a tree diagram to illustrate the possible travel itineraries for Pietro if he can travel from home to Ottawa by bus, car, or train, and then from Ottawa to Orlando by bus, train, or plane.

    3. The attempt at a solution

    bus -train

    . train -train

    plane -train

    Basically, he has 3 choices to go to Ottawa (bus, train, plane) and to go to orlando from Ottawa he has 3 more choices for each. Is this correct?
