Bag A contains two balls, one red and one white and Bag B contains two white balls. A bag is selected at random, and one ball is taken at random from that bag. If the selected ball is white, what is the probability that the other ball in the bag is red? Give your answer as a fraction in its simplest form.

An urn contains 4 white balls and 6 red balls. A second urn contains 6 white balls and 4 red balls. An urn is selected, and the probability of selecting the first urn is 0.8. A ball is drawn from the selected urn and replaced. Then another ball is drawn and replaced from the same urn. If both balls are white, what are the following probabilities? (Round your answers to three decimal places.) (a) the probability that the urn selected...
