(35S) Statistical Distributions Functions

[PedroLeiva]

Dieter, you are absolutely right, my programs calculate the probability for a variable value, not the cumulative probability. The instruction to delete all variables not is correct, I already have erased. Regarding the use of combinatorial calculation function, I did not use it because I decided to test my knowledge of statistics.

I loaded your labels for cumulative Binomial and Poisson function, they work perfectly well.
I wonder why HP says 35s has 800 programation steps, whereas now with 982 still working well ?
