Take a number at random from the interval (i.e., a real number between and ) . Take another number independently, also from . These two numbers are now the coordinates of a point in the plane, and that point lies within the solid square .

If you do this process a second time, you get another point, also within the solid square . The line that connects these two points is the line that separates the two regions in the plane that correspond to the two classes.

Some participants posted plots that show what these look like in other threads.
