There are actually two ten sided dice in a standard 7-dice D&D set. The faces of one are numbered 0 to 9, and the faces of the other go from 00 to 90 by tens. To make a ‘percentile’ roll, you roll both die and add them together, with one exception: a double zero roll is 100.

## How do you roll percentage die?

We roll this die in addition to a D10, We take the number on the D10 and combine it with **the percentage roll** and that equals your percent total. Example: D% is rilled and a 30 comes up. The D10 is rolled and a 3 comes up. 30+3 = 33%.

## Can you roll 0 on d100?

A d100 goes 1–100, a d10 goes 0-9. **Neither allows you to roll a 0**, because of the way you count a percentile dice. (00 on the percentile and a 6 on the other dice forms 6, 00 on one and 0 on the other is 100, no option will result in 0.)

## Why does a d10 have a 0?

The one with two digits is just telling you the tens digit, and the one with one digit is the ones digit. If you’re rolling only that die with 0, 10, 20, etc., then a 10 = a 1 and the 00 = a 10. 0 or 00 on a **d10 just means the highest number**.

## How do you find the percentage of a dice?

So to get a 6 when rolling a six-sided die, probability = 1 ÷ 6 = 0.167, or 16.7 percent chance. So to get two 6s when rolling two dice, probability = 1/6 × 1/6 = 1/36 = 1 ÷ 36 = 0.0278, or 2.78 percent.
