Microstates of a System

Suppose you have four dissimilar balls and two different boxes. How many ways are there to distribute the balls among the boxes?

11+5

(Distribution I and II will transpose to give 5 further arrangements)

Number of the arrangements is the number of microstates of the

system - 16
