      Question

      The probability that Kabir clears an interview is (2/5)

      and the probability that Simran fails is (1/4). Find the probability that both have the same result if both appear.
      A 9/20 Correct Answer Incorrect Answer
      B 11/20 Correct Answer Incorrect Answer
      C 13/20 Correct Answer Incorrect Answer
      D 7/20 Correct Answer Incorrect Answer

      Solution

      Probability that Kabir fails = 1 - (2/5) = (3/5)
      Probability that Simran passes = 1 - (1/4) = (3/4)
      Required probability = (2/5) × (3/4) + (3/5) × (1/4)
      = (6/20) + (3/20) = (9/20)
