Most recent total: 4
How to Use This Calculator
- Press “Roll 2d6” to simulate rolling two six-sided dice.
- Observe die-by-die results, totals, and running averages.
- Use the table to visualize the distribution of recent outcomes.
- Repeat the process to explore probability patterns for sums of two dice.
Formula
Each die outcome is uniform on {1, 2, 3, 4, 5, 6}
Expected value of one die = 3.5
Expected sum of two dice = 7
Probability of total k (2 ≤ k ≤ 12) = number of combinations / 36
Full Description
Rolling two six-sided dice yields sums ranging from 2 to 12, with 7 being the most common outcome. This simulator helps visualize randomness, supports board-game practice, and aids probability lessons.
Frequently Asked Questions
Are successive rolls independent?
Yes. Each roll is independent and uses fresh random values.
Can I roll more than two dice?
This tool focuses on two dice. Look for other calculators tailored to additional dice counts.
Why limit the history to 10 rolls?
It keeps the display manageable. Refresh the page or log totals separately for longer analyses.
Are doubles highlighted?
Not currently. You can easily spot them when both dice show the same number.
