# Random Number Generator 1-100

## Calculator Use

Generate a random number between 1 and 100. Includes a pick counter for multiple draws.

This is a pseudo-random number generator (PRNG) that randomly draws one number at a time from the range of numbers 1 to 100. Each pick is independent of any other pick, meaning each number has an equal chance of being drawn during any given pick.

## Quickly Generate a Random Number 1-100

This random number generator has predefined settings to allow you multiple number picks in a short amount of time.

Range: The range of numbers that the generator picks from is set at the numbers from 1 to 100.

Quantity: Exactly one number is generated at random on each pick.

Repeats: Each pick is independent from the prior pick or the next pick. This means the calculator always randomly picks from a set of 100 numbers, from 1 to 100. So with multiple picks you could theoretically see the same number randomly generated multiple times.

## How to Calculate Probability of Drawing 1 of 100

There are 100 numbers in the range 1 to 100. The probability of any number being drawn at random can be expressed in these terms:

- as a ratio, 1 in 100
- as a division problem, 1/100
- as a decimal, 0.01
- as a percentage, 1%

Each of these terms mean the same thing. So if you have a set of 100 numbers, the chance that any number is drawn at random will be 1 out of 100, or 1%.
