rabbit!ark's solution to the gold-coin problem is correct, but is very
complex.  here's a simple way to explain it:

	there are three gold coins altogether, and i have just found one
	of them.  there is a 2-in-3 chance that it is one of the coins in
	the 2-gold-coins cabinet, since that's where 2 of the 3 are.

	thus there is a 2-in-3 chance that i will see gold in the 2d
	drawer.
