[Tutor] Beginner - explaining 'Flip a coin' bug

[David Hutto]

Here is a problem I've come across, from empirical evidence, that also
relates to your equation. We always assume
 that their are always two probabilities, that a coin can be either head or
tails.

However, there are dynamics within a third realm of the dimensionality of
the coin...it's not a two dimensional plane. So the planar probabilities in
relation to the 'surface are' hold another possibility...the 'edge'.

The algorithm of applying the edge are up to you, but I've seen the coin
land on it's curved edge more than once, so this function you've designed,
should have more than two possibilities, within a complete algorithm to the
real world functionality of the coin in question.
