      Question

      A jar contains five 25 paise coins, ten Rs. 1 coins, and

      ten Rs. 5 coins. One coin was accidentally dropped and lost. Find the probability that the lost coin is not a Rs. 5 coin.
      A 2/5 Correct Answer Incorrect Answer
      B 3/5 Correct Answer Incorrect Answer
      C 1/2 Correct Answer Incorrect Answer
      D 4/5 Correct Answer Incorrect Answer

      Solution

      Number of Rs. 5 coins = 10
      Total number of coins = 5 + 10 + 10 = 25
      So, the required probability = 1 - 10/25 = 15/25 = 3/5
