Calculate the probability of various outcomes for rolling multiple dice. Essential for tabletop RPGs like Dungeons & Dragons.
The probability of an event is the ratio of the number of favorable outcomes to the total number of possible outcomes. For dice, the total outcomes are calculated as (Number of Sides)^(Number of Dice). This calculator determines how many combinations of dice rolls result in your target sum to compute the final probability.
What does "2d6" or "3d8" mean?
This is standard notation in tabletop games like Dungeons & Dragons (D&D). The first number is the quantity of dice, and the second number (preceded by "d") is the number of sides on each die. So, "2d6" means "roll two 6-sided dice," and "3d8" means "roll three 8-sided dice."
Why is rolling a 7 with two 6-sided dice the most common outcome?
Because there are more combinations that add up to 7 than any other number. You can roll a (1,6), (2,5), (3,4), (4,3), (5,2), or (6,1) – that's 6 different ways out of 36 total possibilities, giving it the highest probability (16.67%). In contrast, a 2 can only be rolled one way (1,1).
