    1. 18

    2. {blue, magenta, purple}

    3. P (blue) = 1/2

    P (magenta) = 7/18

    P (purple) = 1/9

    Step-by-step explanation:

    Total balls:

    9 + 7 + 2 = 18

    Sample space: all possible outcomes

    {blue, magenta, purple}

    P (blue) = 9/18 = 1/2

    P (magenta) = 7/18

    P (purple) = 2/18 = 1/9
