how do i tell the difference between a binomial distribution and a poisson distribution?
Since this is not my area of expertise, I searched Google under the key words "binomial poisson distribution" to get these possible sources:
http://en.wikipedia.org/wiki/Poisson_distribution
http://en.wikipedia.org/wiki/Binomial_distribution

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.
I hope this helps. If not, continue the search. Thanks for asking.
