CASE HISTORY -'PENNEY TOSSER'


'Coin Tosser' is being developed (javascript code being rewritten). The game is based upon an amazing contradiction in the mathematical probability relating to the tossing of a coin (a 'penney') -'heads' or 'tails' - an obvious probability of 0.5.

So, given the situation in tossing a coin three times in succession you have a one chance in eight of hitting any one of the eight possible sequences, namely:

HHH, TTT, HHT, TTH, HTT, THH, HTH, THT.


Here is the challenge: whatever sequence of three coins you choose, I will choose an alternative sequence of three.

Then in a random series of tosses my sequence will nearly always come up first. For example if you choose H H T and I choose T H H, and then the coin fell successively T H T H H,
T H H, my choice would win.

Here is but the very first part - practice 'tossing the coin':
