    A piggy bank contains six 50 paise coins, nine Rs. 1 coin,

    and twelve Rs. 2 coins. One of the coins from the piggy bank fell and got lost. Find the probability that the lost coin is not a Rs. 1 coin.
    A 1/2 Correct Answer Incorrect Answer
    B 2/3 Correct Answer Incorrect Answer
    C 1/3 Correct Answer Incorrect Answer
    D 3/4 Correct Answer Incorrect Answer

    Solution

    Number of Rs. 1 coin = 9
    Total number of coins = 6 + 9 + 12 = 27
    So, the required probability = 1 – (9/27) = 2/3
