Suppose that 2000 points are selected independently and at random from the unit square {(x,y) : 0 <= x < 1, 0 <= y < 1}. Let X and Y be random variables for the location of each point. Let W equal the number of points that fall into A = {(x,y) : x^2 + y^2 < 1/2}. (a) What the joint distribution of (X,Y)? (b) Specify the distribution of W, along with its mean, variance and standard deviation. (c) What is the expected value of W/500?
