Consider two urns. Urn contains 2 red and 3 blue balls. Urn contains 4 red and 1 blue ball. A fair die is rolled; if the result is 1 or 2, we pick Urn , otherwise Urn . We draw one ball and it is red. What is the probability that the next ball drawn (without replacement) from the same urn is also red?
