Monte Carlo has many uses, but path tracing is one of my favorites. Part four (thenumb.at/Rendering/) explores how Monte Carlo integration is used to simulate light transport.

Monte Carlo methods require randomly sampling complicated domains, which can be difficult in of itself.
Part three (thenumb.at/Sampling/) discusses how to create samplers using rejection, inversion, and changes of coordinates.
