How it works

A dice roller simulates rolling one or more dice, each face equally likely. For a single fair die the chance of any face is one over the number of sides; rolling several dice and summing produces a bell-shaped distribution centered on the average.

Dice probability

P(any single face) = 1 ÷ sides        Average of one die = (sides + 1) ÷ 2

sides: faces per die (6 for a standard die)

Worked example

Roll two six-sided dice

Each face: 1/6
Most likely sum is 7 (six ways to make it)

Sums range 2–12, with 7 the most common.

Good to know

With multiple dice, middle totals are far more likely than the extremes (you can only make 2 one way).
Each roll is independent — past results don't change the next (no 'due' numbers).
Tabletop notation like 2d6 means 'roll two six-sided dice and add them'.
