Urn I contains 13 red balls and 11 blue balls. Urn II contains 14 red balls and 7 blue balls. Four balls are drawn at random from urn I and placed in urn II. Then five balls are
drawn from urn II. What is the probability that two of the balls drawn from urn I were blue and the
other two were red, given that all the balls drawn from urn II were the same color?
