QUESTION 10 Urn A has 5 white balls and 7 black balls. Urn B has 3 white balls and 12 black balls. A fair coin is flipped. If the outcome is heads, then a ball from Urn A is selected, whereas if the outcome is tails, then a ball is drawn from Urn B. If the ball selected is black, what is the probability that the coin landed heads? O 65 120 O 35 83 41 120 56 83 O O O O
