The expected value for the estimation variable (size), S, can be computed as a weighted average of the optimistic(Sopt), most likely (Sm), and pessimistic (Spess) estimates given as


  1. EV = (Sopt + 4Sm + Spess)/4
  2. EV = (Sopt + 4Sm + Spess)/6
  3. EV = (Sopt + 2Sm + Spess)/6
  4. EV = (Sopt + 2Sm + Spess)/4
