Random Number Generator

What Is the Random Number Generator?

The Random Number Generator picks one or more numbers at random within a range you choose. Set a minimum and a maximum, and each generated number is equally likely to be any whole number in that range, including both endpoints. It is useful for raffles, classroom picks, games, sampling, and deciding who goes first.

For example, with a minimum of 1 and a maximum of 100, each result has a 1 in 100 chance of being any specific number from 1 to 100. Generating again gives a new independent result, so the same number can appear twice in a row by chance.

How to Use the Random Number Generator

1. Enter the minimum value, for example 1.
2. Enter the maximum value, for example 100. The maximum must be greater than the minimum.
3. Choose how many numbers to generate, if the tool offers that option.
4. Choose whether duplicates are allowed or whether each number must be unique, if the tool offers that option.
5. Click Generate.
6. Read the result, and click Generate again for a new draw, or Copy to copy the result.

Worked Example

Suppose you need to pick 3 unique winners from entries numbered 1 to 50:

Set minimum = 1, maximum = 50, count = 3, unique = yes. One possible output is 7, 23, 41. That means entries 7, 23, and 41 win.

Another example: a single draw from 1 to 6 works like a die roll. Each face 1, 2, 3, 4, 5, or 6 has a 1 in 6 chance, about 16.67%.

If duplicates are allowed and you generate 5 numbers from 1 to 10, an output such as 3, 8, 3, 10, 1 is valid because 3 appears twice.

Limitations

• The generator is a browser tool for everyday draws. It is not designed for cryptographic keys, secure tokens, gambling, or lotteries that require audited randomness.
• True fairness depends on the range being correct. If you enter 1 to 100 but your entries are numbered 0 to 99, the draw will not match your list.
• You cannot generate more unique numbers than exist in the range. Asking for 10 unique numbers from 1 to 5 is impossible.
• Results are not saved. Copy or note the result before generating again or leaving the page.
• Random does not mean evenly spread in a small sample. In 10 draws from 1 to 100, some ranges may appear more often purely by chance.

Frequently Asked Questions

Is the minimum and maximum included?

Yes. Both endpoints are included. A range of 1 to 10 can return 1, 10, or any number in between.

Can the same number appear twice?

Yes, when duplicates are allowed. Each draw is independent. Turn on unique-only mode if you need every number to be different.

Can I generate decimal numbers?

This tool generates whole numbers. If you need decimals, use a range and divide, for example generate 0 to 100 and divide by 100 to get 0.00 to 1.00 in steps of 0.01, or use a dedicated decimal generator.

Is the result fair for a raffle?

For an informal raffle, yes, provided the entry numbers match the range exactly and the draw is done openly. For a prize draw with legal or financial stakes, use a method that meets your local rules and keeps a verifiable record.
