A twenty-something single person is planning a ski vacation. Assume that he has 4 possible destinations: Utah, Colorado, Oregon, and New England. There are 4 ski areas in Utah with 2 available times for 3 of the areas, and 1 times for the other area. There are 4 ski areas in Colorado with 2 available times for 3 of the areas, and 3 times for the other area. There are 2 ski areas in Oregon with 4 available times for 1 of the areas, and 1 times for the other area. There are 2 ski areas in New England with 1 available times for 1 of the areas, and 3 times for the other area. (A "time" refers to a weekend for which there are vacancies at the ski lodge.) A trip plan involves the selection of a location, ski area, and a time.
