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 - 133. A bag contains 3 white, 3 black and 2 red balls. One by one three balls are drawn without replacing them. The probability that the third ball is red, is : (a) 1/2 (b) 1/3 (c) 2/3 (d) 1/4
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 - 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
