To download this binomial probability calculator, as a standalone program, right-click here, and
“save link as,” or “save target as,” or similar. It is written in Perl, so you'll need to have Perl installed to use it.
On Windows I use Strawberry Perl, but most other recent version 5 Perls should also
work.

(It is a work in progress, so there are no warranties, express nor implied, but you can contact me
if you have difficulty.)

^{1} For example, if `perl binomcalc.pl m=cu a=s n=50000 k=10 p=1/10000`”

^{2} Calculating cumulative probabilities for k=100 requires calculating binomial probabilities for 101 different
values of k, and summing them.

^{3} This mainly affects the Experimental settings. For example, if
`perl binomcalc.pl m=acu a=x n=35750 k=5 p=1/10000` b=1”
