I'd be grateful if someone could post it, I can't find it. It was something about a professor and two students being late to class, blaming it on a car accident. He gave them a make up test with two questions, one of them was which tire/wheel got damaged? Or something along those lines. Please refer if you know what I am talking about. Thanks.

What does this have to do with probability? What does it have to do with mathematics? –  Gerry Myerson Jul 30 '12 at 0:12
    
Are we supposed to find the question or to answer it or what? –  Gigili Jul 30 '12 at 0:26

I found this by googling for student excuse car accident probability quiz which wheel. It's in Essentials of Statistics:

Flat Tire Excuse: A classic excuse for a missed test is offered by four students who claim that their car had a flat tire. On the makeup test, the instructor asks the students to identify the particular tire that went flat. If they really didn't have a flat tire and randomly select one that supposedly went flat, what is the probability that they will all select the same tire?

The problem is incompletely specified; presumably a uniform distribution over the tires is implied.
