My boss wants me to use poisson probabilities to compute the liklihood of
meeting various goals in relation to our project, where the average number
of records per month is 617,000.

I am having trouble getting Excel to compute probabilities as other than 0
or 1, though when I do examples on the web that involve very small numbers I
get teh correct answers with no trouble.

Are poisson probabilities intended for this use? Or are they only
applicable for small numbers of discrete events, like the liklihood that 4
cars will run a traffic light in a day?

What would be the appropriate statistic for the probability of meeting a
goal of 700,000 discrete events in a month, or a few million in a year?
