Binomial
Binomial is a ruby gem for quickly calculating probabilities that are modeled by the Binomial Theorem.
The master branch of this repo may be rather buggy at times. For a stable version, use gem install binomial
or download a tagged version.
Usage
require 'binomial'
calc = Binomial::Calculator.new trials: 10, probability: 0.2, target: 3
# Returns the probability of 3 successes occuring during 10 trials where the
# probability of a success is 0.2
calc.calculate
