Random Number Picker — Examples
Examples, context and typical uses for Random Number Picker.

If duplicates are permitted, drawing several numbers is like replacing each number after it is chosen. Unique drawings remove a selected value from the pool.
Avoid bias
Use a clear selection rule before seeing any generated number; changing the rule afterward can bias decisions.
