tricky ps

by runzun » Fri Dec 09, 2011 8:05 am
Six mobsters have arrived at the theater for the premiere of the film "Goodbuddies." One of the mobsters, Frankie, is an informer, and he's afraid that another member of his crew, Joey, is on to him. Frankie, wanting to keep Joey in his sights, insists upon standing behind Joey in line at the concession stand, though not necessarily right behind him. How many ways can the six arrange themselves in line such that Frankie's requirement is satisfied?

6

24

120

360

720



The correct answer is D.

The answer is 0. Joey hired Benny who takes out Frankie, in a drive by, before Frankie gets in line.

Of course it's a joke. The problem was about mobsters.
