The Coin Flip: A Fundamentally Unfair Proposition?


"The 50-50 proposition is actually more of a 51-49 proposition, if not worse. The sacred coin flip exhibits (at minimum) a whopping 1% bias, and possibly much more. 1% may not sound like a lot, but it's more than the typical casino edge in a game of blackjack or slots. What's more, you can take advantage of this little-known fact to give yourself an edge in all future coin-flip battles."

I got 34:16 (T:H) by spinning a 2p coin 50 times. Oddly including a run of six heads.
