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?
The probability of drawing a white ball from the first urn is 9/18 = 1/2.
The probability of drawing a white ball from the second urn is 8/11.
To find the probability of both balls being white, we multiply the probabilities of drawing a white ball from each urn:
(1/2) * (8/11) = 4/11
Therefore, the probability that both balls drawn are white is 4/11.
