monte carlo simulation

A Ruby Monte Carlo simulation of coin flips

For some reason or another today I was curious about this question: If you flipped a coin ten times, what are the odds that the coin would come up heads ten times, or tails ten times)?

I'm sure there is a way to determine this statistically, but I don't know how to do that, so, being new to Ruby, I wrote a little Ruby simulation program — essentially a Monte Carlo simulation of the problem — to find the answer. (Pretty boring, I know, but hey, I was bored, interested in learning Ruby, and didn't feel like reading any more of The Stand right now.)

A Java Monte Carlo simulation for my “Minority Report” problem

Introduction

This Java Monte Carlo simulation tutorial, and the corresponding Java program, was inspired by the story and subsequent movie "Minority Report", as well as my recent interest in Monte Carlo simulations.
