Two urns contain white balls and yellow balls. The first urn contains 9 white balls and 9 yellow balls and the second urn contains 8 white balls and 3 yellow balls. A ball is drawn at random from each urn. What is the probability that both balls are white?

They're independent events, so you just multiply the probabilities for the individual urns.

The events are independent. The outcome of the first draw does not affect the outcome of the second draw.

 P(white1 and white2) = P(white1)*P(white2) = (9/18)*(8/11) = 4/11. @KeemoD143
