Making the cut. In 1988, the ignition keys for Ford Escorts were made out of a blank key with five cuts, each cut made of one of five different depths. How many different key types were there? In 1988, Ford sold roughly 380,000 Escorts. What is the probability that one Escort key will unlock a random Escort? (This story was reported in the April 1989 issue of the Atlantic Monthly.)
