Dice Probability Basics:
From: | To: |
Dice probability calculates the chance of getting a particular sum when rolling multiple dice. With standard six-sided dice, each die has equal probability (1/6) for each face.
The calculator determines the probability using combinatorial mathematics:
Where:
Details: With two dice, sums of 7 are most likely (6/36), while 2 and 12 are least likely (1/36 each). The distribution becomes more normal (bell-shaped) with more dice.
Tips: Select number of dice (2-5) and enter your target sum. The calculator shows the probability as percentage and fraction.
Q1: What's the most likely sum for 2 dice?
A: 7 is the most probable sum with 6/36 (1/6) probability.
Q2: What sums are possible with 5 dice?
A: The possible range is 5 (all 1s) to 30 (all 6s).
Q3: Why does probability distribution change with more dice?
A: More dice create more possible combinations that produce middle sums, making extreme sums less likely.
Q4: Can I calculate exact probabilities for more than 5 dice?
A: Yes, but the calculations become more complex. This calculator focuses on 2-5 dice for practicality.
Q5: How accurate are these probabilities?
A: They're mathematically exact assuming fair, standard six-sided dice.
