WebMarkov chains are simply a set of transitions and their probabilities, assuming no memory of past events. Monte Carlo simulations are repeated samplings of random walks over a set of probabilities. You can use both together by using a Markov chain to model your probabilities and then a Monte Carlo simulation to examine the expected outcomes.
