Bag A contains 4 white and 7 black balls. Bag B contains 5 white and 6 black balls. A die is rolled . If 2 or 5 turns up then choose bag A otherwise choose bag B. If one ball is drawn at random from the selected bag, then find the probability that it is black.

Bag A contains 4 white and 7 black balls. Bag B contains 5 white and 6 black balls. A die is rolled. If 2 or 5 turns up then choose bag A otherwise choose B. If one ball is drawn at random from the selected bag, then find the probability that it is black.

Bag I contains 3 black and 2 white balls, bag II contains 2 black and 4 white balls. A bag and a ball is selected at random. Determine the probability of selecting a black ball.

A bag 'A' contains 6 white and 7 black balls while the other bag 'B' contains 4 white and 5 black balls. A ball is transferred from the bag A to the bag B. Then a ball is drawn from the bag B. Find the probability that the ball drawn is white.
