10-Sided Dice Roller Calculator

Enter how many 10-sided dice to roll and generate random results instantly, including totals and average outcomes.

Random seed:

Results: 1, 4, 1, 6, 3

Total: 15

Average: 3.00

How to Use This Calculator

  1. Specify how many 10-sided dice (d10) you want to roll.
  2. Click the roll button to generate new random outcomes.
  3. Review the list of rolls, total sum, and average value.
  4. Repeat rolls to simulate scenarios for tabletop games or probability exercises.

Formula

Each die is uniformly distributed over integers 1 through 10.

Expected value of one die: (1 + 10) / 2 = 5.5

Total expected value for n dice: 5.5 × n

Standard deviation of one die: √[(10² − 1) / 12] ≈ 2.87

Standard deviation for n dice: 2.87 × √n

Full Description

Rolling a 10-sided die (d10) yields values from 1 to 10 with equal probability. This tool simulates independent rolls, useful for tabletop gaming, probability demonstrations, or random number generation exercises.

The calculator records sums and averages to illustrate how outcomes aggregate as more dice are rolled.

Frequently Asked Questions

Does each roll resemble a physical d10?

Yes. Each result from 1 to 10 is equally likely, mirroring a fair 10-sided die.

Can I track history of rolls?

Current results display only the latest roll. Repeat the action to simulate multiple scenarios.

Why show a seed?

The seed indicates the timestamp used to generate the random outcome, useful for reproducibility discussions.
