The random selector has been rigorously tested through simulations and a statistical analysis was performed on the outcomes to ensure it is doing its job of giving each item an equal chance of being picked on any particular draw.

What it does is equivalent to rolling a fair dice with as many sides as there are things in your list - each one has an equal probability to be picked. This is a pseudo-random number generator (PRNG) that randomly draws one number at a time from the range of numbers 1 to 10. Our random picker can handle lists of up to 10,000 things.įinally, simply press the "Pick Randomly" button and let our randomizer do its job.
