LSAT time rapidly approacheth, and I know that future law students can't get their hands on enough practice questions. So, over the next few weeks, I'll be offering up some more LR and LG practice problems. The first person to post a full set of right answers in the comments gets a free BuffaloWings&Vodka bumper sticker and their name scrawled on the wall in the men's bathroom across from the Tom C. Clark Lounge on the first floor of the UT law school.
We'll start off easy. Enjoy.
During a long night of post-exam drinking, four law students--Jesus, Keanu, Lothar, and Mikey--make their way to a men’s room that contains five adjacent urinals--1, 2, 3, 4, and 5--and two stalls--A and B. Each of the law students has had three liters of beer in the last hour and must relieve himself immediately. They proceed according to the following restrictions:
--No student will choose a urinal that is immediately adjacent to an occupied urinal unless no other urinal is available and both stalls are full.
--If Mikey is at a urinal, Keanu will choose a stall.
--If Jesus chooses a urinal, then Mikey will also choose a urinal.
--Lothar will always choose a urinal.
--If Mikey is in a stall, then Keanu will choose an even-numbered urinal.

5. Assume that Mikey loses his WWJP? bracelet and is no longer bound to choose a urinal whenever Jesus does. If urinal 5 is broken, and stall A is too dirty for anyone but Keanu to use, but all other conditions remain the same, how many possible arrangements of students at urinals and/or in stalls are there?
