      Question

      Bag A contains 4 red and 6 blue balls, while Bag B

      contains 7 blue and 5 yellow balls. If one ball is drawn from bag 'A' and bag 'B', respectively, at random, then what is the probability that both balls drawn are blue?
      A 1/3 Correct Answer Incorrect Answer
      B 7/20 Correct Answer Incorrect Answer
      C 2/5 Correct Answer Incorrect Answer
      D 3/10 Correct Answer Incorrect Answer

      Solution

      Probability of drawing a blue ball from Bag A = (6/10)
      Probability of drawing a blue ball from Bag B = (7/12)
      Required probability = (6/10) Γ— (7/12) = (42/120) = (7/20)
