  Subj: Probability routines (HP48)
  Date: Fri Jun 28 1991

Below is an HP48SX directory full of probability routines.  However, I'm only
half way through the course right now so I'll add the rest as I go along.
Although most of these routines are pretty simple, downloading them is much
easier than typing them all in yourself.

However, I'm not sure about the Poisson distribution function for Lambda large.
In my textbook it describes a computer program that will calculate this
distribution function for any value of Lambda.  However, using the formulae
they suggest gives me answers just like using the summation of the Poisson
density function, instead of the answers they give in their example of the
program running.  So if you figure out how it is supposed to work (supposing my
distribution function is incorrect), let me know.
