    For the last part using geometric probability, why are we able to say that the side lengths are 1/2 even though we're looking for cases when the difference between x and y is greater than 1/2? Wouldn't the sides of the triangle be less than 1/2 and the overall area is smaller than what we found?
    Thank you in advance.

      The side length is 1/2 - an infinitesimal (1/infinity) or in other terms a single point because this point doesn’t have a donate length the side then is 1/2.
