    Question

    A money bag has eight 50 paise coins, seven Rs. 2 coins,

    and ten Rs. 10 coins. If one coin falls out and is lost, what is the probability that the lost coin is not a Rs. 2 coin?
    A 18/25 Correct Answer Incorrect Answer
    B 7/25 Correct Answer Incorrect Answer
    C 2/5 Correct Answer Incorrect Answer
    D 3/4 Correct Answer Incorrect Answer

    Solution

    Number of Rs. 2 coins = 7
    Total number of coins = 8 + 7 + 10 = 25
    So, the required probability = 1 - 7/25 = 18/25
