Two persons decided to go for a horse ride. But who will ride first? The horse was in stable. They decided to work out the solution with a chance. As they enter the stable, is the "head" of the horse facing us or is the "tail" of the horse facing us?. So, one called "Heads" and the other automatically settled for "Tails". This is how they decided who will ride the horse first - a chance with two equally likely probabilities. Does this initiate the history of the terms "heads or tails"? Regards Atul
