Raphael Cautain submitted a Comment to Problem 331. Compute Area from Fixed Sum Cumulative Probability

A really nice problem : concrete origin, careful formulation, then a good walk in 3D geometry, analysis, integration and at the end a single formula. The critical value cuts the triangle in four pieces : my son said it was Zelda !
