Answer 1

Answer:

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%

2/39

Step-by-step explanation:

Two urns contain white balls and yellow balls. The first urn contains 2 white balls and 7 yellow balls and the second urn contains 3 white  balls and 10 yellow balls. A ball is drawn at random from each urn. The probability that both balls are white is 2/39.
