    Trouble with a binomial distribution formula

    So,

    I've tried everything I can think of, and I can't seem to get any kind of answer from my TI-83 plus, excel or wolfram. I've done several of these before without a problem, so I'm not sure whats going on.

    Here's the data:

    n=11,000,000 p=0.0000008, x= (ranging from 0 to 12)

    Anyone have any ideas?

    Thanks in advance.

    That is not a question. It is several statements.
    Please state the exact question as given in the text.

    Construct a binomial distribution for n=11,000,000 p=0.0000008, x= 0 to 12.

    That looks like a very highly contrived question in a numerical analysis class. The number of trials is so large and the probability of success so small as to render most standard programs useless. I suggest that look for a site that specialties in precision calculations. I know such sites must exist. As many as twenty years ago, I reviewed a text book to be used in precision BASIC.

    If you can settle for a close approximation instead of an exact result, consider a Poisson distribution.
