Probability

Question

An unfair coin with pr[H]=2/3 is flipped. If the flip results in a head, then a marble is selected from an urn containing 6 red, 9 white, and 5 blue marbles. If the flip results in a tail then a marble is selected from an urn containing 5 red and 7 white marbles. If the marble selected is white, then what is the probability that a flip resulted in a head?
