- a 90 degree angle triangle. The 001 triangular distribution
          which expresses an estimate that the lowest value is the most likely; for
          example, you believe that the next-day quoted delivery date is most likely
          (knowing that a quicker delivery is impossible - the postman only comes

          is assumed to never take more than your upper limit.
