I can't resist responding- it is because the coin only has two sides, that
"two-out-of-three" tosses
is the preferred practice for enculturing the coin, as an artifact, into a
particular
a social game (the duality of heads/tails produces a third interaction:
2-out-of-3 tosses).
The third side of the coin is the outer ridge. Stand a quarter on its edge.
