Urn 1 contains 5 white balls and 7 black balls. Urn 2 contains 3 whites and
12 black. A fair coin is flipped; if it is Heads, a ball is drawn from Urn 1, and
if it is Tails, a ball is drawn from Urn 2. Suppose that this experiment is
done and you learn that a white ball was selected. What is the probability
that this ball was in fact taken from Urn 2? (i.e., that the coin flip was Tails)
