1.	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
A.	EV = (Sopt + 4Sm + Spess)/4
B.	EV = (Sopt + 4Sm + Spess)/6
C.	EV = (Sopt + 2Sm + Spess)/6
D.	EV = (Sopt + 2Sm + Spess)/4
Answer» C. EV = (Sopt + 2Sm + Spess)/6
