Understanding Probability & Dice Rolls
Use our dice roller as an educational tool to explore fundamental concepts in probability theory, statistics, and game design.
Uniform Distribution
Each face of a fair die has an equal probability of appearing. For a standard 6-sided die, each number (1-6) has a 1/6 chance (~16.67%).
Formula: For a die with n sides, each face has probability = 1/n. For a 6-sided die: 1/6 ≈ 16.67%
Law of Large Numbers
As you roll more dice, the actual distribution of outcomes will converge closer to the theoretical probability of each face appearing equally.
Try it: Roll 10 dice, then 100, then 1,000. Notice how the percentages get closer to 16.67% for each number with larger sample sizes.
Independent Events
Each dice roll is completely independent. Previous rolls have zero influence on future outcomes - the die has no memory!
Important: Even after rolling three 6s in a row, the next roll still has exactly a 1/6 chance of being any number.
Sum Probabilities
When rolling multiple dice, certain sums are more likely than others. The probability distribution forms a bell curve (normal distribution).
Example: With two 6-sided dice, rolling a 7 is most common (1+6, 2+5, 3+4, 4+3, 5+2, 6+1 = 6 ways), while rolling a 2 or 12 is rare (only 1 way each).
Expected Value
The expected value (average) of a fair 6-sided die is 3.5. For multiple dice, multiply by the number of dice rolled.
Calculation: Expected value = (1+2+3+4+5+6)/6 = 3.5. For 3 dice: 3 × 3.5 = 10.5 average sum.
Polyhedral Dice
Our roller supports 4, 6, 8, 10, 12, and 20-sided dice. Each has different probability distributions and expected values.
Popular in: Tabletop RPGs like D&D use various dice (d4, d6, d8, d10, d12, d20) for different game mechanics and damage calculations.
