Question
Given a simple Project like the one pictured above. Optimistic / Most Likely / Pessimist Times were assessed and Path Means and Path Standard Deviations were calculated. For Path 1-2-5 we have a Path Mean = 28 and a Path Standard Deviation = 3. For Path 1-3-4-5 we have a Path Mean = 23 and a Path Standard Deviation = 2. Determine both the Probability that Path 1-2-5 will finish in 28 Days or Less and the Probability that the Project will finish in 28 Days or Less.

(A)0.977249938 : 0.977249919
(B)0.747507533 : 0.747333608
(C)0.5 : 0.49689516
(D)0.908788718 : 0.908785627
Explanation / Answer
Path 1-2-5 is the longest path as compared to others, have mean = 28 and standard deviation = 3. Therefore the probability that path 1-2-5 will finish in 28 days or less and that the project will finish in 28 days or less is ( c) 0.5; 0.49689516 approx. 0.5
