    Rs. 5 coins in a pouch. One coin is lost. Find the probability that the lost coin is not a Rs. 1 coin.

    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
