    Okay so the probability of drawing a blue bean is

    8 / 29 = .276

    29 is the total number of jelly beans

    When we have replacement, we do not reduce the number of total jelly beans, so the probably of drawing blue stays the same.

    But to find the probability of drawing a blue two times in a row, we must square the probability .

    (.276) • (.276) = 0.076

    Your answer is 7.6% !
