The software lets users randomly pick items and remove duplicates from large lists with thousands of entries. Different probabilities can be assigned to each item and items can be picked in groups or individually. There are many options and commands, including the ability to pick same items multiple times, randomizing and equalizing the chances, sorting, shuffling, etc. The program supports easy export and import to/from text files and other programs, and has full clipboard support. The product is ideal for randomly selecting people - students or employees for various tests, like drug tests for example. It can be used whenever one needs to take a random sample or make a subset out of a bigger set.
