Mathematical and Physical Examination of the Locality Condition in   Bell's Theorem
  Using the Clauser-Horne model of Bell's theorem, the locality condition is examined and it is shown the corresponding formulation is equivalent to a factorization process consisting of three stages. The first stage is introduced based on the conditional probability definition in classical theory of probability and the other two stages are based on previously-known relations named as outcome and parameter independence conditions.
