Question 529901: There are three urns that each contain 10 balls. The first contains 3 white balls and 7 red balls, the second 8 white and 2 red, and the third all 10 white. Each urn has an equal probability of being selected. After an urn is selected a ball is randomly drawn from this urn. If the ball drawn was white, find the probability that the third urn was selected. (Round your answer to three decimal places.)
