Assume three points, one of which is red, are uniformly and independently distributed over the circum ference of a circular track, which has a total length of 1. Equivalently, you can interpret the circle as a unit interval with its two ends tied together, and all distances of points are measured in terms of the length on the track. The Figure below gives a simple illustration. 1. Let X be the distance of the red point to its neighbor in...

3. In a Monte Carlo method to estimate T, we draw n points uniformly on the unit square [0, 1]2 and count how many points X fall inside the unit circle. We then multiply this number by 4 and divide by n to find an estimator of T (a) What is the probability distribution of X? b) What is the approximate distribution of 4X/n for large n? (c) For n- 1000, suppose we observed 756 points inside the unit circle....
