Consider the system consisting of a pair of Einstein solids in thermal contact. A certain macropartition has a multiplicity of 1.2 x 10^346, while the total number of microstates available to the system in all macropartitions is 5.9 x 10^362. If we look at the system at a given instant of time, what is the probability that we will find it to be in our certain macropartition?
