Discover the Birthday Paradox.

Overview

Birthday Grapher helps users discover the Birthday Paradox. Like many people, when I was first introduced probability's infamous "Birthday Paradox" I was in strong disbelief. I saw the formula and accepted it, but never really got it.

Recently I decided to convince myself of the validity of the paradox through the creation of a simple computer program. What this program does is takes a test-pool (or what I call a "room") and for each "person" in the "room" picks a number from 1 to 365. Then it checks to see if there are any duplicate numbers and returns "1" if there are and "0" if there aren't. Then it repeats this process a user specified number of times until it finally averages all of the ones and zeros together to produce a probability.

For the fun of it, I decided to have the program graph whole ranges of room-sizes to show the really unintuitive behavior of this problem.

This program doesn't do much, but it does what it says it will pretty well. It's worth taking a look at.
