An urn contains 8 white balls and 2 red balls. A second urn contains 2 white balls and 8 red balls. An urn is selected, and a ball is randomly drawn from the selected urn. The probability of selecting the first urn is 0.65. If the ball is white, find the probability that the second urn is selected.

An urn contains 2 white balls and 8 red balls. A second urn contains 8 white balls and 2 red balls. An urn is selected, and a ball is randomly drawn from the selected urn. The probability of selecting the first urn is 0.1. If the ball is white, find the probability that the second urn was selected. (Round your answer to three decimal places.)
