A bag X contains 2 white and 3 black balls and another bag Y contains 4 white and 2 black balls. One bag is selected at random and a ball is drawn from it. The, the probability chosen to be white is a. 2//15 b. 7//15 c. 8//15 d. 14//15

A bag A contains 2 white and 3 red balls another bag B contains 4 white and 5 red balls. A bag is chosen at random and a ball is drawn from it. If the ball drawn is red, what is the probability that the bag B is chosen? [CBSE '04C)

A bag A contains 3 white and 2 black balls and another bag B contains 2 white and 4 black balls. A bag and a ball out of it are picked at random. What is the probability that the ball is white?

A bag contains 3 white and 2 black balls and another bag contains 2 white and 4 black balls. One bag is chosen at random. From the selected bag, one ball is drawn. find the probability that the ball drawn is white.

A bag contains 3 white and 2 black balls and another bag contains 2 white and 4 black balls. One bag is chosen at random. From the selected bag, one ball is drawn. find the probability that the ball drawn is white.

A fair die is rolled. If a face 1 turns up, a ball is drawn from Bag A. If face 2 or 3 turns up a ball is drawn from Bag B. If face 4 or 5 or 6 turns up, a ball is drawn from Bag C. A contain 3 red and 2 white balls, Bag B contains 3 red and 4 white balls and Bag C contains 4 red and 5 white balls. The die is rolled, a Bag is picked up and a ball is drawn. If the drawn ball is red, what is the probability that it is drawn from Bag B?

A bag contains 4 red, 6 black and 5 white balls, A ball is drawn at random from the bag. Find the probability that the ball drawn is: white

Bag 4 contains 3 red and 2 white balls, and Bag B contains 2 red and 5 white balls. A bag is selected at random, a ball is drawn and put into the other bag, then a ball is drawn from the second bag. Find the probability that both balls drawn are of the same colour.

A bag contains 6 black and 3 white balls. Another bag contains 5 black and 4 white balls. If one ball is drawn from each bag, find the probability that these tow balls are of the same colour.
