Consider a system of two particles. Each particle can be in one of three possible microstates: one ground state (E = 0, call it "G") and two excited states (both with E = E, call them "A" and "B"). (a) List the possible states that this system can be in if both particles are bosons. (For example, "GG", "GA", and "AB" are three possibilities. Remember that AB and BA are the same state since these are indistinguishable particles.) Then write the partition function Z of this system as a function of β. (b) Now do the same thing if the particles are fermions.
