Consider a gas confined to a container that can be divided into two compartments of equal volume. If one compartment initially contains N1 identical molecules at energy E1 and the other compartment contains N2 identical molecules at energy E2, what is the probability that the molecules will eventually be distributed equally between the two compartments? Use statistical mechanics and thermodynamic ensembles to calculate this probability.
