  1. I got 1/3 for red
    I got 2/3 for yellow
    and 1/3 for green but they was wrong, Since you only have three colors I put that on the bottom and went by equal numbers on top. Can someone explain this to me.

  2. Hints:
    Work out the following:

    - equal numbers of red marbles and yellow marbles (call
    x=number of red
    x=number of yellow

    - twice as many green marbles as red marbles
    2x=number of green

    Now work out the sample space and the corresponding probabilities.

    Hint for you.
    If you provide attempted answers to the question, do add "(answer check)" to the end of "school subject", especially if you have a whole series of questions which makes it look it homework dumping.
