    7/12
    So we first need to add up all the marbles so there are 12 marbles to pick from so we know that there is 7 orange marbles and since there are only three colors and two of them we don’t want pick there is a 7/12 chance of getting a marble that isn’t yellow or blue and since we can’t simplify any further that’s the answer
