Consider an isolated system of 3 distinguishable, non-interacting atoms that occupy a set of 3 energy levels which are equally spaced by one energy unit. Assume that the ground state has zero energy, how many microstates are compatible with the macrostate if the total energy of the system is 3 energy units?
