There are four activities on the critical path, and they have standard deviations of 1, 2, 4, and 2. what is the probability that the project will be completed in 38 weeks if its expected completion time is 40 weeks? select one: a. 0.26 b. 0.35 c. 0.58 d. 0.76

Standard deviations of the four activities of the critical path are 1,2,4,2.

Standard deviation of this critical path = Sum of square root of variance of this corresponding critical path

Standard deviation of critical path

Now we need to find the probability that the project will completed in 38 weeks given that its expected completion time is 40 weeks.

That is, we need to find P(X<38) :

Probability

Thus the probability that the project will be completed in 38 weeks is 0.34.

4th option is correct xy=-10
