Aproject being analyzed by pert has 38 activities, 16 of which are on the critical path. if the estimated time along the critical path is 90 days with a project variance of 25, what is the probability that the project will be completed in 88 days or less?

required probability is .3446

Step-by-step explanation:

It is given that most expected time of completion = 90 days

Variance = 25

We know that

Thus the standard normal deviate is given by

Applying values we get

Using the standard table for Z we have probability corresponding to Z = -0.4 equals 0.3446

Thus required probability is .3446

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
