    Answer:

    1 / 9

    Step-by-step explanation:

    Choosing with replacement means that the first draw from the lot is replaced before another is picked ‘.

    Number of Blue marbles = 2

    Number of red marbles = 4

    Total number of marbles = (2 + 4) = 6

    Probability = required outcome / Total possible outcomes

    1st draw :

    Probability of picking blue = 2 / 6 = 1 /3

    2nd draw :

    Probability of picking blue = 2 / 6 = 1/3

    P(1st draw) * P(2nd draw)

    1/3 * 1/3 = 1/9
