@HpDarkman,
Quote: if you had a machine that flipped a coin with a precise force into a vacuum, you could have it flip heads again and again every time.
Flipping a coin is usually not done in a vacuum. It's also not usually done by machines. For all intent and purposes, an honest human being flipping a coin within the earth atmosphere behaves as a random event, if only because there are so many uncontrolled variables at play. Of course the tosser can cheat and fake the flipping, it's quite easy to do in fact.
