      Question

      The probability that Riya passes the test is (4/9) and the

      probability that Aditya fails is (1/3). If both appear for the test, find the probability that they both get the same result.
      A 13/27 Correct Answer Incorrect Answer
      B 11/27 Correct Answer Incorrect Answer
      C 17/27 Correct Answer Incorrect Answer
      D 5/9 Correct Answer Incorrect Answer
      E 19/27 Correct Answer Incorrect Answer

      Solution

      Probability that Riya fails = 1 - (4/9) = (5/9)
      Probability that Aditya passes = 1 - (1/3) = (2/3)
      Required probability = (4/9) × (2/3) + (5/9) × (1/3)
      = (8/27) + (5/27) = (13/27)
