An urn contains 10 white and 3 black balls.Another urn contains 3 white and 5 black balls.Two balls are drawn from the first urn and put into the second urn and then a ball is drawn from the second urn.Find the probability that ball drawn from 2nd urn is white.

An urn contains 10 white and 3 black balls.Another urn contains 3 white and 5 black balls.Two balls are drawn from the first urn and put into the second urn and then a ball is drawn from the second urn and the probability that ball drawn from 2nd urn is white.

One urn contains 4 white and 2 black balls. Second urn contains 5 white and 4 black balls. Two balls are transferred from the first urn to the second urn. Then one ball is drawn from the second urn. Find the probability that it is white.

The first of two urns contains 3 white and 2 black balls and 2 red balls. One ball is taken at random from the first urn and is placed in the second urn. Then if one ball is taken at random from the second urn, find the probabilities that it is either red or white.

The first of two urns contains 3 white and 2 black balls and 2 red balls. One ball is taken at random from the first urn and is placed in the second urn. Then if one ball is taken at random from the second urn, find the probabilities that it is black.

There are three urns containing 2 white and 3 black balls, 3 white and 2 black balls and 4 white and 1 black balls, respectively. There is an equal probability of each urn being chosen. A ball is drawn at random from the chosen urn and it is found to be white. Find the probability that the ball drawn was from the second urn.

Two urns A and B contain 6 black and 4 white, 4 black and 6 white balls respectively. Two balls are drawn from one of the urns. If both the balls drawn are white, find the probability that the balls are drawn from urn B.

Two ums contain respectively 2 red,3 white and 3 red,5 whiteb balls.One ball is drawn at random the first urn and transferred into the second.A ball is now drawn from the second urn and it turns out to be red Find the probabiliy that the transferred ball from first urn was white.
