 OFFSET 0,2 COMMENTS The solution to the problem proposed and solved by Enoch Beery Seitz in 1882: "A cube is thrown into the air and a random shot fired through it; find the chance that the shot passes through the opposite side." The corresponding probability for the 2D case is 1/2 - log(2)/Pi = 0.279364...
