    21 rotten bananas are accidentally mixed with 135 good

    ones. It is not possible to just look at a banana and tell whether or not it is rotten. One banana is taken out at random from this lot. Determine the probability that the banana is taken out is a good one.
    A 41/52 Correct Answer Incorrect Answer
    B 45/57 Correct Answer Incorrect Answer
    C 45/52 Correct Answer Incorrect Answer
    D 45/52 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    Numbers of bananas = Numbers of rotten bananas + Numbers of good bananas тИ┤ Total number of bananas = 135 + 21 = 156 bananas P(E) = (Number of favourable outcomes) / (Total number of outcomes) P(picking a good banana) = 135/156 = 45/52┬а
