The points (x,y,z) of the sphere x 2 y 2 z 2 = 1, satisfying the condition x = 05, are a circle y 2 z 2 = 075 of radius on the plane x = 05 The inequality y ≤ 075 holds on an arc The length of the arc is 5/6 of the length of the circle, which is why the conditional probability is equal to 5/6 This successful geometric explanation may create the illusion that the following. (Note this used the a=1, b=2, r=3 example from before, so we got it right!) Unit Circle If we place the circle center at (0,0) and set the radius to 1 we get (x−a) 2 (y−b) 2.
