    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
