The Range 0–3 in Numbers

N = 3 − 0 + 1 = 4
P = 1 ÷ 4 = 25%
Whole numbers in the range 4
Chance of each number 1 / 4 = 25%
Even / odd numbers 2 / 2
Chance of an even number 2 / 4 = 50%
Draws for a particular number to reach a 50% chance 3

With repeats allowed, each draw misses a particular number with probability 1 − 1/4, so after k draws it has appeared at least once with probability 1 − (1 − 1/4)k. That first reaches 50% at k = 3.

4 equally likely outcomes — the same odds as one roll of a 4-sided die (d4) from a tabletop game set.

Random Number Generator

This generator picks a random whole number between two bounds, both of them included. The number is drawn in your browser from its cryptographic random source, and every number in the range has the same chance. For example, it can help you find out random number between 0 and 3? Enter the lower bound (e.g. '0') and the upper bound (e.g. '3'), then press 'Generate'. On the result page you can draw several numbers at once, with or without repeats.

FAQ

Random number between 0 and 3?

It can be any of the 4 whole numbers from 0 to 3, each with a 25% chance

How many numbers are there from 0 to 3?

4 whole numbers: 3 − 0 + 1 = 4, because both bounds are included. Even numbers among them: 2, odd: 2 — so an even result comes up with a 50% chance.

How many draws does it take to get a particular number from 0 to 3?

With repeats allowed, a particular number has at least a 50% chance of appearing once it has been given 3 draws; after 2 draws the chance is still below 50%. Each draw is independent, so earlier misses do not make it «due».

How to pick several different numbers from 0 to 3?

Set how many numbers you need and tick «No repeats». The generator then draws without replacement, so you can get up to 4 different numbers — the whole range in random order.

What has the same odds as a random number from 0 to 3?

4 equally likely outcomes — the same odds as one roll of a 4-sided die (d4) from a tabletop game set.
