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!).(adsbygoogle = window.adsbygoogle || []).push({});

I'll go first:

Problem:

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

Solution:

(c)
