Math.binomial_distribution(tries: 1, probability: 0.4, success: 1) # => 0.4
NormaleDistribution::between      standard_deviation: 15, esperance: 100, a: 85, b: 115 # => 0.6826894921370859
NormaleDistribution::less_than    standard_deviation: 15, esperance: 100, a: 85 # => 0.15865525393145707
NormaleDistribution::greater_than standard_deviation: 15, esperance: 100, a: 115 # => 0.15865525393145707
