Suppose you have three boxes with 10 drawers each. The first box has
10 silver coins, the second box has 9 silver coins and 1 gold coin,
and the third box has 10 gold coins.

Now you pick a box, open a drawer, and find a gold coin. Now you have
eliminated the first box, so there's a fifty-fifty chance that it's
either the second or third box ... right?
