Bag I contains 3 red and 4 black balls and Bag II contains 4 red and black balls. Two balls are transferred at random from Bag I to Bag II and then a ball is drawn from Bag II. The ball so drawn is found to be red in colour. Find the probability that the transferred balls were both black.

Bag I contains 3 red and 4 black balls and Bag II contains 4 red and 5 black balls.One ball is transferred from Bag I to Bag II and then a ball is drawn from Bag II.The ball so drawn is found to be red in colour.Find the probability that the transferred ball is black.

Bag A contains 4 red,3 white and 2 black balls.Bag B contains 3 red,2 white and 3 black balls.One ball is transferred from bag A to bag B and then a ball is drawn from bag B The ball so drawn is found to be red.Find the probability that the transferred ball is black.

Bag A contains 3 red and 5 black balls,while bag B contains 4 red and 4 black balls.Two balls are transferred at random from bag A to bag B and then a ball is drawn from bag B at random.If the ball drawn from bag B is found to be red,find the probability that two red balls were transferred from A to B.

Bag A contains 3 red and 5 black balls,while bag B contains 4 red and 4 black balls.Two balls are transferred at random bag A to bag B and then a ball is drawn from B at random.If the ball drawn from bag B is found to be red, find the the probability that 2red were transferred from A to B

Bag I contains 5 red and 4 white balls and bag II contains 3 red and 3 white balls Two balls are transferred from the bag I to the Bag ll and then one ball is drawn from bag ll lf the ball from the bag II is red then find the probability that one red ball and one white ball are transferred from the bag l to the bag II

A bag contains 4 red and 4 black balls,another bag contains 2 red and 6 black balls.One of the two bags is selected at random and a ball is drawn from the bag which is found to be red.Find the probability that the ball is drawn from the first bag.
