What is the Random Number Generator?
A random number generator produces an unpredictable number within a range you choose. It's used for drawing lottery or raffle numbers, picking a winner fairly from a list, assigning random samples in research, generating game outcomes, or simply making an unbiased decision when you can't choose between options yourself.
How to Calculate
Set a minimum and maximum value — the generator picks uniformly at random from everything in that range (inclusive), so every number has an equal chance of being selected. Run it again for a fresh independent draw; each result doesn't depend on the one before it.
Formula
Uniform random selection between min and max.
