Making unfair coins
|Can you make a coin that falls, on average, heads more often than tails?|
I'll leave you to think of a way of adapting an existing coin or making one from scratch. I expect you can be put in the Tower of London and boiled in oil for defacing coins of the realm so don't try to bribe a policeman with one of your creations.
Now we come to the interesting bit. How are you going to test it? Ah yes. I hadn't thought of that. Do you make a machine? In any event does the way you toss the coin affect the result? Ok I relent:- Try a good one side by side with your special.
During your experiments you may find you have a knack of throwing that has a bias with a good coin.
