Our last example for this section introduces the idea of a run, a notion that arises in statistics-in particular, in the detecting of trends in a statistical process. The counter at Patti and Terri's Bar has 15 bar stools. Upon entering the bar Darrell finds the stools occupied as follows: O O E O 0 0 0 EEE O O O E O, where O indicates an occupied stool and E an empty one. (Here we are not concerned with the occupants of the stools, just whether or not a stool is occupied.) In this case we say that the occupancy of the 15 stools determines seven runs, as shown: 00 E 0000 EEE O00 E O Run Run Run Run Run Run Run In general, a run is a consecutive list of identical entries that are preceded and followed by different entries or no entries at all. A second way in which five E's and 10 O's can be arranged to provide seven runs is E O 0 O E E OO E O 0 0 0 0 E. We want to find the total number of ways five E's and 10 O's can determine seven runs. If the first run starts with an E, then there must be four runs of E's and three runs of O's. Consequently, the last run must end with an E. Let x1 count the number of E's in the first run, x2 the number of O's in the second run, x3 the number of E's in the third run,..., and x, the number of E's in the seventh run. We want to find the number of integer solutions for Xi + x3 + xs +x7 - 5, X1, X3, xs, X7 >0 (3)
