This project uses some concept that will be detailed here.
There is no square. A rectangle is a polygon (quadrilateral with a length and a width).
If you add points, coordinates then it is a cartesianRectangle.
Those simple rectangle can't really be compare, however you can compare there area or perimeter.
For not conditional probabilities.
Standard would be:
P(A and B) = P(A) * P(B)
Standard would be:
P(A or B) = P(A) + P(B) - P(A and B)
Morgan's law would be to look at neither A and B to get A or B:
P(A or B) = not P(not A) and P(not B)
