ProbabilityChecker
==================

[](#probabilitychecker)

Pretty simple probability implementation that can be used for A/B testing. If you have some feature that you want to run on 20% of the requests. This is right tool for you as you do not need to define how many requests there will be in total.

If you provide 0 as a parameter, it will always return false, if you provide 100, it will always return true. Everything in between will be around the number you provided.

**Note:** This method is not exact but approximation, so if you want 20%, you will get 21%, 23% maybe 18%, but at the end it will be around 20% (the greater number of request, more accurate will be the percentage).
