12) There are two boxes, A and B. Box A contains 4 blue balls and 6 red balls, while box B contains 7 blue balls and 3 red balls. We choose a box randomly and draw a ball out of it. The probability of choosing box A is 1/3. Suppose a blue ball is drawn. Find the probability that it came from box A.
