Abstract
Recently, Gates described several simulation experiments in an attempt to demonstrate the superiority of Gates. model over Friedman.s model to determine the probability of winning a construction contract letting. This note explains why Gates. paper misrepresents Friedman.s model; does not display a sound comprehension of the basic tenets f probability; misinterprets the results from an unnecessary simulation; and wrongly pronounces the validity of Gates. model. The reader is assumed to have read Gates. paper, as references to equations and tables in it shall be made.
