Urn I contains 2 white and 3 black balls. Urn II contains 3 white and 2 black balls. One ball is selected at random from Urn I and transferred to Urn II. Next, one ball is selected at random from Urn II and transferred back to Urn I. Finally, a ball is drawn at random from Urn I. What is the probability that this final ball is white?
