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

✅ The correct answer is option B.
Explanation: This assumes that there is a very small probability that the actual size result will fall outside the optimistic or pessimistic values.
