Monte Carlo simulations, named after the famous gambling hub of Monaco, have become an indispensable tool for tackling complex problems involving uncertainty and risk. These simulations harness the power of random sampling to estimate the probability of various outcomes, providing valuable insights into decision-making processes.
Monte Carlo simulations work by repeatedly generating random samples from a probability distribution. These samples are then used to estimate the expected value, variance, and other statistical properties of the underlying problem. By simulating a large number of scenarios, the simulation can provide a comprehensive picture of the possible outcomes and their likelihood.
