Random Number Generator

Both ends of the range count

The minimum and maximum are both possible results, so 1 to 10 draws from ten values and 0 to 10 from eleven. For a die-like draw of 1 to 6, enter exactly that. The range can hold up to 4,294,967,296 values, enough for any raffle ticket or row number, and negative numbers work as long as the minimum is not above the maximum.

Repeats come sooner than expected

Every number is drawn independently, and duplicates appear surprisingly early. Drawing 10 numbers from 1 to 100 gives about a 37% chance that at least two match, and 23 draws from 365 values pass 50%, the same arithmetic as the birthday problem.

When every result must be different, such as several raffle winners, write the ticket numbers into the list shuffler and take the first few, or skip a repeat and draw again. Either way, fix the range and the rule before drawing so the result cannot be questioned afterwards.

How to use it

1. Set an inclusive minimum and maximum.
2. Choose how many numbers you need.
3. Generate and copy the result.
