    2/39

    Step-by-step explanation:

    2 of the 9 balls in the first urn are white. 3 of the 13 balls in the second urn are white. The probability that a ball randomly selected from each are both white is the product:

    P (A and B) = P (A) P (B)

    P = (2/9) (3/13)

    P = 2/39

    P ≈ 5.13%
