Simulating a fair coin November 14th, 2008 by Hang
A couple of months ago, I stumbled upon the question of how thick you would need to make a cylinder for it to be a fair three sided coin. Well, not having the patience to roll a cylinder 1000 times, I whipped up a quick simulation:
Turns out the height needs to be ~1.33 times the radius for there to be an exact equal chance to land on 3 sides.
So now you know.
