Understanding your calculation

Method, example and limitations

How the calculation works

A fair die gives every face the same theoretical chance. Multiple independent dice produce sums with different probabilities because some totals have more combinations.

Example to check

Two fair six-sided dice have 36 ordered outcomes. Six sum to 7, while only one sums to 2.

Before using the result

Random simulations fluctuate over short runs. Do not use this tool for regulated gambling or a drawing requiring an independently audited random process.
