Download Solution PDFConcept:
Probability can be calculated by using probability factor (Z) which is defined as,
\(Z=\frac{T_s-T_e}{\sigma}\)
where, Ts = Schedule completion time
Te = Expected completion time
\(\sigma=\) Standard deviation
Z = Probability factor depending on probability
Calculation:
Given: Te = 20 days, \(\sigma=4days\)
For 84.13 %, Z = 1
\(1=\frac{T_s-20}{4}\)
\(T_s=20+4=24days\)
