A Monte Carlo simulation requires assigning multiple values to an uncertain variable to achieve multiple results and then averaging the results to obtain an estimate.Monte Carlo simulations help to explain the impact of risk and uncertainty in prediction and forecasting models.A Monte Carlo simulation is a model used to predict the probability of a variety of outcomes when the potential for random variables is present.
In other words, with a Monte Carlo simulation the goal is to simulate the collection of all or many possible paths (using random sampling) in order to find the possibilities and the most likely or theoretical solution. This is due to the sample being more representative of the population as the sample become larger. The Law of large numbers states that as a sample size grows, its mean gets closer to the average of the whole population. Monte Carlo simulations are used to model the probabilities of different outcomes where those outcomes are hard to predict due to random variables.
