a) Write the partition function
b) Write the average energy by taking the derivative, and
explain why it is the normal average formula, i.e. sum e_i p_i
c) Now imagine there are N copies of this system - what is the
partition function assuming they are independent? What is the
average energy of the whole system in terms of the second
system?
d) Out of the N, how many do you expect to have energy E_b?
