# Random Number Generator

## Calculator Use

Generate one or more random number or random letter sets from a range of numbers or letters respectively.

The random numbers or letters will be the random sample set. For **Sample Size** enter the value for the number of samples you want chosen. For the **Sample Range** enter the range of values to randomly choose from. For example, to choose from **1** to **100** enter **1-100**; to choose from **a** through **m** enter **a-m or A-M**.

If the sample size is greater than the sample range and duplicates are not allowed, the number of results will be limited by the range.
