The 50g also has the NDIST(m,v,x) function which might be of some use to you. It returns the normal probability distribution (bell curve) at x based on the mean m and variance v.

Just guessing here... if not applicable, please ignore this reply.

Hi Joe!
I will take a look at UTPN and NDIST.
I was making a webpage for it.{

I got these formulas from my Casio FX-5000F.
They work!

This is the corrected formula.
Thanks to Mike and Trojdor for help.
