## Dice Probability Formulas

The following formulas are used to calculate different dice probabilities. (6 sided dice)

- Chance to get any given value (sum of all dice)
- C = 1 / 6 * D
- Where D is the number of dice

- C = 1 / 6 * D
- Change to get matching values on all dice. (i.e. 1/1/1 on 3 dice)
- C = (1 / 6 ) ^ D
- Where D is the number of dice

- C = (1 / 6 ) ^ D
- Chance to get at least 1 value on a role of D number of dice.
- C = D / 6
- Where D is the number of dice

- C = D / 6

These formulas are only used for 6 sided dice. For different-sided dice, you must change the value 6 to the number of sides on the dice.

## Dice Probability Definition

Dice Probability is defined as the chance of an event occurring while rolling 1 or more dice.

## Dice Probability Example

How to calculate dice probability?

**First, choose the event.**Choose which outcome you wish to calculate the probability of.

**Next, determine the probability.**Based on the event you chose, calculate the probability of that happening when you roll the dice.

## FAQ
