Extracted text: 1. A parking lot has seven spaces for seven cars. The spaces are next to each other and the ones on each end has only one neighboring space while each of the others have two. What is the probability that when three cars park one after the other and at random, they do not have any neighbors? Naturally, no two cars can occupy the same space.
