Suppose that we have two urns, cleverly named .2 Urn I and Urn II. Suppose that Urn I has 2 red marbles and 2 blue marbles, and Urn II has 1 red and 3 blue marbles. We flip a fair coin to select an urn. If head occurs, Urn I is selected, otherwise, Urn II. Having selected an urn we select a marble without looking in the urn. It so happens that the marble we chose is red. Our question is: what is the ?probability that we chose Urn I
