Q.  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: See Answer
 
This assumes that there is a very small probability that the actual size result will fall outside the optimistic or pessimistic values.
