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 $=25$ and a Path Standard Deviation $=3.$ For Path $1-3-4-5$ we have a Path Mean $=21$ and a Path Standard Deviation $=4.$ Determine both the Probability that Path $1-2-5$ will finish in $25$ Days or Less and the Probability that the Project will finish in $25$ Days or Less.
