Probability » Exercise - 129. One bag contains 5 white & 4 black balls . Another bag contains 7 white and 9 blac k balls . A ball is transferred from the first bag to the second and then a ball is drawn from second . The probability that the ball is white is : (a) 8/17 (b) 40/153 (c) 5/9 (d) 4/9

Probability » Exercise - 125. A bag A contains 2 white & 3 red balls & bag B contains 4 white & 5 red balls. One ball is drawn at random from a randomly chosen bag and is found to be red. The probability that it was drawn from bag B was : (a) 5/14 (b) 5/16 (c) 5/18 (d) 25/52

Probability » Exercise - 136. A bag contains 3 red, 4 white and 5 blue balls. All balls are different. Two balls are drawn at random. The probability that they are of different colour, is : (a) 47/66 (b) 10/33 (c) 5/22 (d) none of these

Probability » Exercise - 1 1. Two balls are drawn at random with replacement from a box containing 10 black and 8 red balls. Find the probability that both balls are red ? (a) 8/81 (b) 16/81 (c) 20/81 (d) 40/81

Probability » Exercise - 19. If P (A) = 0.4, P (B) = x, P (A ∪ B) = 0.7 and the events A & B are independent, then x = (a) 1/3 (b) 1/2 (c) 2/3 (d) none of these
