# Unusual way to achieve π: Generating Pi from random numbers
The purpose of this repo is to gather (programming) solutions for the peculiar procedure for generating / achieving [π (Pi)][Pi] that [Matt Parker] presented in [this video][Video].
## Why
1. In commemoration for [Pi Day] 2017.
2. Having fun.
3. No apparent logic reason.
## How does it work
Since the **Probability of Two (random) Integers Being [Coprime][Coprime integers]** is given by:
 [Proof and demonstration]
We can generate lots of numbers and calculate π by:
Watch Matt Parker generating π from 1,000 random numbers by rolling a dice on [here][Video full].
## Acknowledgments
All solutions are from these users (in no particular order), some are quite efficient others not so much. Regardless thanks very much.
