Monte Carlo Simulation ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],The method samples  randomly  from a universe of possible outcomes and takes  the fraction of random draws  that fall in a given set as an estimate of the set’s measure. The Law of Large Numbers  guarantees the  convergence  of the  estimation to the correct value as the number of draws increases.
