Monte Carlo simulation often refers to the estimation of means using averages. For example, we can estimate the number π by sampling points in a 2d square with vertices at {(1, 1), (1,−1), (−1, 1), (−1,−1)}. Defining an event A as 1 if the sampled point lies inside the unit circle and 0 otherwise, we have E[A] = area of the circle area of the square = π 4 , so we can estimate π by the ratio of number of points inside the circle over total number of points.
