    How to find out distribution's mode?

    Link: http://i39.tinypic.com/14n2t0o.png

    For 1c) It asks to give the distribution's mode. Well I never recall learning that anywhere on the book. How would I figure out what is the mode of it?
    I figured out the table as soon below:
    P(0) = 2.016e-8
    P(1) = 9.8428e-7
    P(2) = 0.000021625
    P(3) = 0.00028155
    P(4) = 0.0024056
    P(5) = 0.014094
    P(6) = 0.057343
    P(7) = 0.15998
    P(8) = 0.29291
    P(9) = 0.3178
    P(10) = 0.15516
    But nowhere does any of those numbers match up to one another to be called a mode. So this has gotten me really confused.

    *For 1B) Is the answer All real numbers?
    *For 1D) Is the answer P(9) = 0.3178?

    Thank you so much for your time!

    *For 1B) Is the answer All real numbers? Mr F says: No.
    *For 1D) Is the answer P(9) = 0.3178? Mr F says: Yes.

    1B) The support is x = 0, 1, 2, ..... 10.

    1C) The mode is n = 9 (why? Go back and look at the definition. The answer to 1D) is salient).
