Frequently Asked Questions
Is 1-3 generation fair for making three-way decisions?
Yes. Each number (1, 2, or 3) has exactly a 33.33% chance of being selected — perfectly equal odds. This is mathematically provable thanks to our use of cryptographic randomness with rejection sampling.
What are common uses for a random number between 1 and 3?
Popular uses include choosing between three options, assigning people to three groups, picking a winner from three finalists, Rock-Paper-Scissors resolution, and any scenario where you need to randomly select from three choices.
Can I type a custom count, like 6 numbers between 1 and 3 at once?
Yes — the "How many?" box accepts any count from 1 to 1,000 (type 6, 25, 500…), and the quick buttons fill common values. Turn on "No duplicates" when every number must be unique.
How many possible results are there in the 1 to 3 range?
Exactly 3 (counting both 1 and 3). Each has an identical 1-in-3 chance (33.33%) of appearing on every draw, independent of previous results.
