Click the number or press Generate — 50 possible outcomes
?Generating a random number from 1 to 50 means every integer has a 1-in-50 (2%) chance. The expected average result is 26. This range is widely used for percentage-based probabilities, exam simulations, and game mechanics.
Probability: Each number from 1 to 50 has exactly 2% probability on every roll. This is a discrete uniform distribution — there is no bias toward any particular value, and past results never influence future ones.
Common uses for this range: Percentage-based probability, guessing games, random selection from up to 50 items, statistical demonstrations.

Click the large number or press Generate. A random integer between 1 and 50 is selected with 2% probability for each value. You can also adjust the range using the fields above.
Yes. Math.random() in modern browsers uses a cryptographically seeded algorithm producing a uniform distribution. Each of the 50 integers between 1 and 50 has exactly equal probability.
The statistical mean of the range 1 to 50 is 26. Over many rolls, your results will converge toward this value. The standard deviation is approximately 14.43.
