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.

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.

An urn A contains 2 white and 3 black balls. Another urn B contains 3 white and 4 black balls.Out of these two urns, one is selected at random and a ball is drawn from it. If the ball drawn is black, then the probability that I. It is from urn A is 21/40, II. It is from urn B is 20/41 . Which of the following statements is correct

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.

An urn contains 10 red and 8white balls.One ball is drawn at random.Find the probability that the ball drawn is white.

An urn contains 10 red and 8 white balls. One ball is drawn at random. Find the probability that the ball drawn is white.

An urn contains 10 red and 8 white balls. One ball is drawn at random. Find the probability that the ball drawn is white.

Suppose that an, urn B_(1) contains 2 white and.3 black balls and another urn B_(2) contains 3 white and 4 black balls. One urn is selected at random and a ball is drawn from it: If the ball drawn is found black, find the probability that the urn chosen was B_(1).
