Dice Probability Explained
1. Single Die Odds
| Dice | Average Roll | Probability Distribution |
|---|---|---|
| d6 | 3.5 | Equal 16.67% per side |
| d20 | 10.5 | Flat 5% chance per number |
2. Multiple Dice Math
- 2d6 → Bell curve (Most common: 7)
- 3d6 → 16 possible totals (Peak at 10-11)
Formula for Average:

Avg = (Min + Max) ÷ 2 Example: d20 → (1 + 20)/2 = **10.5**
3. D&D Advantage/Disadvantage
| Roll Type | Avg d20 Roll |
|---|---|
| Normal | 10.5 |
| Advantage (roll 2, keep highest) | 13.82 |
| Disadvantage (roll 2, keep lowest) | 7.18 |
