    Probability (I hate this stuff!)

    A "true false" exam has 10 questions. Assuming that the questions are independent and that a student is guessing, find the probability that she gets 100%.

    The probability for each question (independant event) is .5
    There are ten.
    Thus,
    (.5)^10=0.0009765625
    Same as saying,
    .0976565%
