    The probability that the next word she speaks is correct is 16/17,.9412, or 94.12%.

    Step-by-step explanation:

    First find the probability of getting a word incorrect, this is done by taking the number of words incorrect and subtracting that from the total. Then taking the difference and putting it over the total.

    p (correct) = (102-6) / 102

    p (correct) = 96/102

    p (correct) = 16/17

    p (correct) = 0.9412

    Therefore the probability that the next word she speaks is correct is 16/17,.9412, or 94.12%.
