Homework Statement
A system has non-degenerate energy levels with energy[tex] \epsilon=(n+1/2)\hbar\omega [/tex] where h-bar*omega=1.4*10^-23J and n positive integer zero what is the probability that it is in n=1 state with a heat bath of temperature 1K
Homework Equations
[tex]
Z=\exp^\frac{-E_i}{k_b T} \\
p_r=\frac{\exp^\frac{-E_i}{k_b T}}{\sum^N_j \exp^\frac{-E_j}{k_b T}}
[/tex]
The Attempt at a Solution
I'm not really sure what to do now, I don't know how to sum the total number of states to get the fraction of states in the n=1 state
