Comprehensive Calculator Guide
This calculator gives the chance of a total with one or more six-sided number cubes, plus at most and at least, and the number of ways. With two cubes, 7 is the likeliest total: 6 ways out of 36. It is a teaching tool for counting outcomes and seeing how distributions take shape.
Counting ways
n cubes have 6^n equally likely outcomes. Middle totals form in more ways, so the distribution grows bell-shaped as cubes are added.
How to Use
- Enter the number of cubes (1–20).
- Enter the target total.
- Press “Calculate” to see the chances.
Formula Used
P = ways ÷ 6^n
Practical Examples
- Example 1
- 7 with two cubes: 16.67%.
- Example 2
- 10 with three: 12.5%.
Important Tips
- Draw a 6 × 6 table to check.
- Roll and compare in class.
- The peak is near 3.5 × cubes.
Common Mistakes to Avoid
- Treating (1, 6) and (6, 1) as one.
- Assuming equal totals.
- Totals outside the range.
