GRE (physics) practice problems

  1. Jun 11, 2008 #1
    Hey, I think it would be beneficial for many if we started a thread that contained several problems (and hopefully solutions as well) that would be helpful in studying for the GRE. So, everyone, add a problem if you can (with solution!).
    I'll go first:

    A sample of N atoms of helium gas is confined in a 1.0 cubic meter volume. The probability that none of the helium atoms is in a $1\times 10^{-6}$ cubic meter volume of the container is:
    (a) 0
    (b) (10^{-6})^N
    (c) (1-10^{-6})^N
    (d) 1-(10^{-6})^N
    (e) 1

    It would be more helpful if you can show how You arrived at that solution. :biggrin:
