A die is rolled and showing any number is directly proportional to that number. If prime number appears then a ball is chosen from urn `A` containing 2 white and 3 black balls otherwise a ball is chosen from urn `B` containing 3 white and 2 black balls Then.
The probability of drawing a black ball is

A bag contains 5 white and 4 black balls and another bag contains 7 white and 9 black balls. A ball is drawn from the first bag and two balls drawn from the second bag. What is the probability of drawing one white and two black balls ?

A bag contains 4 white balls and 3 black balls. If two balls are drawn at random, then mean of number of white balls is

Bag A contain 4 white balls and 3 black balls, while Bag B contain 3 white balls and 5 black balls. Two balls are drawn from Bag A and placed in bag B. Then, what is the probability of drawing a white ball from bag B ?
