The property you can observe macroscopically is the fration of black and white balls on either side. What happens when you pull out the barrier in the middle and why? How much higher is the multiplicity of a fully-mixed arrangement (equal numbers of black and white on both sides). Calculate the entropy for the unmixed system, and the entropy for achieving a fully mixed solution. (hint: you must calculate Omega(left) and Omega(right) to get the total number of states, Omega).
