A) 0.841
B) 0.919
C) 0,964
D) 0.977
Correct Answer: A
Solution :
Critical path: \[1-2-4-5\] Critical time = 23 days Standard deviation, \[\sigma =\sqrt{{{2}^{2}}+(2.8)+{{2}^{2}}}\] = 3.98 \[z=\frac{27-23}{3.98}=1\] For z = 1, area under the normal distribution curve = 0.8413 Probability of completing the project =0.841You need to login to perform this action.
