    2/3

    Step-by-step explanation:

    Total number of marbles = 3 + 4 + 5 = 12

    Pr (red marble) 3/12

    Pr (Blue marble) = 4/12

    Pr (white marble) = 5/12

    Probability of drawing either a red or a white marble

    = Pr (red) + Pr (white)

    = 3/12 + 5/12

    = 8/12

    = 2/3
