Consider throwing a dart at the origin of the Cartesian plane. You are aiming at the origin, but random errors in your throw will produce varying results. We assume that: 1.) The errors do not depend on the orientation of the coordinate system. 2.) Errors in perpendicular directions are independent. This means that being too high doesn't alter the probability of being off to the right. 3.) Large errors are less likely than small errors. Let...
