Pi via Rand

Inspired by standupmaths video https://www.youtube.com/watch?v=RZBhSi_PwHU

My question: If you could increase the sides of the dice (keeping # of dice rolls constant), would it actually improve the calculation of Pi?

Answer: Not really, 120 sided dice was probably good enough, you just need more rolls of the dice.

Pi via 500 n-sided dice throws Pi via n 120-sided dice throws

Google spreadsheet with data and nice charts: https://goo.gl/Mkoqf6

Sample size was 4096 for both tests

  • 4k samples of n-sided dice with 500 rolls
  • 4k samples of n-rolls with 120-sided dice

To run:

  • install golang
  • go get github.com/montanaflynn/stats
  • go run main.go
