Sides per die

Target sum

Roll one die and every outcome is equally likely — a flat distribution. Roll several and sum them, and the shape becomes a bell: middle sums have many combinations, extremes have few. This is the central limit theorem in miniature, and why 7 is the most common roll of two dice and the heart of the game of craps.

Governing equation

E [sum] = \frac{n ( d + 1 )}{2} = \frac{2 ( 6 + 1 )}{2} = 7.0

Reading this result: Your target sits right at the peak: sums near the mean of 7 have the most combinations while the extremes have just one each — the central limit theorem in miniature.

About this simulation

The full Dice Probability tool models a regression forecast with the same numerics engineers and scientists use — running entirely client-side. Change any parameter and the result updates in real time, so you can build intuition, check a design, or teach the concept without spreadsheets or installs.
