For example, for a given m, as we
make n large (and p small), the binomial distribution becomes
like the Poisson distribution.

If the mean, m increases to a large value,
both the binomial and Poisson distributions become more
symmetrical and can be approximated by a Gaussian distribution.

To set s for the Gaussian, type a
value in the rectangle and hit 'submit'.

Vary
parameters to find when the binomial distribution approaches the
Poisson distribution or when all 3 distributions are similar.
