Dice types
| Die | Sides | Common uses |
|---|---|---|
| d4 | 4 | Small weapon damage in RPGs |
| d6 | 6 | Board games, Yahtzee, craps |
| d8 | 8 | RPG damage rolls |
| d10 | 10 | Percentile rolls (with a second d10) |
| d12 | 12 | Large weapon damage |
| d20 | 20 | D&D attack rolls and ability checks |
| d100 | 100 | Percentile tables |
Two-dice probabilities (2d6)
| Total | Ways | Chance |
|---|---|---|
| 2 or 12 | 1 | 2.8% |
| 3 or 11 | 2 | 5.6% |
| 4 or 10 | 3 | 8.3% |
| 5 or 9 | 4 | 11.1% |
| 6 or 8 | 5 | 13.9% |
| 7 | 6 | 16.7% |
That's why 6s and 8s are prized in Catan, and why 7 matters so much in craps.
Average roll
The average of one die with n sides is (n + 1) ÷ 2: 3.5 for a d6 and 10.5 for a d20. For several dice, multiply by the number of dice: 2d6 averages 7.
