      Question

      The probability that Dev clears the exam is (3/10) and the

      probability that Kriti fails is (1/6). What is the probability that both of them have the same result?
      A 11/30 Correct Answer Incorrect Answer
      B 13/30 Correct Answer Incorrect Answer
      C 3/10 Correct Answer Incorrect Answer
      D ½ Correct Answer Incorrect Answer
      E 17/30 Correct Answer Incorrect Answer

      Solution

      Probability that Dev fails = 1 - (3/10) = (7/10)
      Probability that Kriti passes = 1 - (1/6) = (5/6)
      Required probability = (3/10) Ă— (5/6) + (7/10) Ă— (1/6)
      = (15/60) + (7/60) = (22/60) = (11/30)
