Returns the probability from a Poisson distribution.

The POISSON function
returns the probability that an observation from a Poisson distribution,
with mean m, is less than or
equal to n. To compute the
probability that an observation is equal to a given value, n, compute the difference of two probabilities
from the Poisson distribution for n and n−1.
