A D5 (five-sided die) generates a random number between 1 and 5. Physical five-sided dice are uncommon, so players typically simulate a d5 by rolling a d10 and dividing by 2 (rounding up). This virtual dice roller makes d5 rolls quick and accurate.
How To Use The D5 Roller
- Set the number of times you want to roll
- Set how many D5 dice to roll per attempt
- Click "Roll dice" to generate your results
- View individual roll results or the grand total
Common Uses For D5 Dice
- Random weekday selection: Choose a random weekday (Mon-Fri)
- Small tables: Random selection from 5 options
- Custom game mechanics: House rules that need 5-way probability
- Rating systems: Generate random 1-5 star ratings
D5 Probability
Each result on a D5 has an equal probability of 20% (1/5):
| Result | Probability |
|---|
| 1 | 20% |
| 2 | 20% |
| 3 | 20% |
| 4 | 20% |
| 5 | 20% |
The expected average roll is 3 when rolling a single D5.
Simulating D5 With Other Dice
If you don't have a virtual d5 roller, you can simulate one:
- D10 method: Roll a d10, divide by 2, round up (1-2=1, 3-4=2, 5-6=3, 7-8=4, 9-10=5)
- D10 method 2: Roll a d10, reroll on 6-10, use result directly
