Imagine a box on points (2,6),(6,6),(2,1),(6,1) the area of this box is 5•4=20 now subtract the areas of the four triangles in between the box and the parallelogram for all four triangles, the area is 3•1/2=1.5 20-1.5-1.5-1.5-1.5=14
Because in the theory of the outcome is a 50/50 chance landing heads or tails. So, the theorectical probability is 1/2. Now the experimental must be 11/20.
