They'll be independent, just not equally

Mind you, they won't be independent. For example, if I had to pick
one, what would I pick? I'd think about the other students and
imagine which they'd pick. The

6 students, 4 tires:
The probability that they all choose the same tire [doesn't matter which] is
(1/4)^5 = 1/1024.
N students, M tires:
(1/M)^(N-1)

probability that they all choose the front left-hand tire?)
