      Question

      There are five Rs. 1 coins, four Rs. 2 coins, and fifteen

      Rs. 5 coins in a pouch. One coin is lost. Find the probability that the lost coin is not a Rs. 1 coin.
      A 5/6 Correct Answer Incorrect Answer
      B 7/8 Correct Answer Incorrect Answer
      C 3/4 Correct Answer Incorrect Answer
      D 19/24 Correct Answer Incorrect Answer

      Solution

      Number of Rs. 1 coins = 5
      Total number of coins = 5 + 4 + 15 = 24
      So, the required probability = 1 - 5/24 = 19/24
