Question 1181903: If there are 100 typographical errors randomly distributed in a 500-page manuscript, find the probability that a given page contains exactly 3 errors. (Please round to three decimal places)

There are 0.2 errors per page as the mean.
That is the Poisson parameter (this kind of problem is Poisson--mass function, counts proportional to number of trials, theoretical possibility of infinite numbers of errors per page)
p(3)=e^(-0.2)*0.2^3/3!
=0.0011 or 0.001
