Input Examples

Value

In General...
All inputs are positive numbers
Portions can't be greater than wholes

Binomial

The Binomial Distribution gives the probability of 'X' successes, where:
• 'X' is a number or range of numbers (integer only)
• 'Probability' is the chance of each event happening
• The probability of each 'success' denoted in 'X' is equal
• For each 'X' tested, the same event is not tested again (like taking cards from a deck without replacing).

Hyper-Geometric

The Hyper-Geometric Distribution gives the probability of 'X' successes, where:
• 'X' is a number or range of numbers (integer only)
• 'Pop. Success' is the number of successes in the greater population from which the sample is taken
• 'Pop. Size' is the size of the greater population from which the sample is taken
• Result is the same whether expressed as fraction or decimal

Poisson

The Poisson Distribution gives the probability of 'X' successes, where:
• 'X' is a number or range of numbers (integer only)
• 'Lambda' is the expected value of x

Negative Binomial

The Negative Binomial Distribution gives the probability of 'X' successes, where:
• 'X' is an integer
• 'Failures' the number of tries before reaching success.
• 'Probability' is the chance of each event happening
