Well, here goes my first post here, thought this might be of some help for role playing games..
Dice Probability Generator
Description
Using this engine, you can calculate the odds of various outcomes of dice rolls, along with the actual number of permutations that occur.
Methods and examples
1. Probability of a total sum for all dice
Selections : Sum of dice, number of dice, sides of dice
Example: For 20d10 getting the sum of 110, there is a 3% chance, or 3.08 * 10 ^ 18 permutations
2. Probability of a total sum or less for all dice
Selections : Sum of dice, number of dice, sides of dice
Example: For 6d8 getting the sum of 38 or lower, there is a 98.1% chance, or 257181 permutations
3. Probability of a total sum or greater for all dice
Selections : Sum of dice, number of dice, sides of dice
Example: For 49d20 getting the sum of 500 or higher, there is a 64.4% chance, or 3.62 * 10 ^ 63 permutations
4. Probablility of a certain number rolled for a specific number of dice
Selections : Specific number of dice with the number, number of dice, sides of dice
Example: For 5d of 8d4 getting a 3, there is a 2.3% chance, or 1512 permutations
5. Probability of a specific number or higher rolled for a specific number of dice
Selections : Specific number of dice with the number, number of dice, sides of dice, specific number
Example: For 5d of 8d4 getting a 3 or higher, there is a 21.8% chance, or 14336 permutations
6. Probability of a specific number or lower rolled for a specific number of dice
Selections : Specific number of dice with the number, number of dice, sides of dice, specific number
Example: For 2d of 2d20 getting a 7 or lower, there is a 12.2% chance, or 49 permutations
7. Probability of a certain number rolled for a specific number or more of dice
Selections : Specific number of dice, number of dice, sides of dice
Example: For 4d or more of 6d6 getting a 5, there is a 0.87% chance, or 406 permutations
8. Probability of a certain number or higher rolled for a specific number or more of dice
Selections : Specific number of dice, number of dice, sides of dice
Example: For 4d or more of 6d6 getting a 5 or higher, there is a 10% chance, or 4672 permutations
Controls
Arrow keys: Move to a different calculation or description circle.
Spacebar, C: Select circle
Z: Change background music
X: Show options for quitting dice probability calculator.
Alt + Enter: Enter/Exit fullscreen mode
Notes
Odds are given in permille, or parts per thousand, or ppm, parts per million. Permille is 1/10th of a percent, while ppm is 1/10000th of a percent.
While I tried to eliminate all possible opportunities for human error, there may still be some left over, so unusual results may possibly be achieved for unrealistic scenarios, i.e. rolling the sum of 30 with 2d6.
