An activity being analyzed under PERT was judged to most likely have a duration of 40 days. When considering the time it would take to complete the activity if every relevant factor went well, it was estimated to be able to be doable in 20 days and even under the worst case imaginable, the task would be take 50 days. The estimates PERT duration of that activity is:

38.33 days

Explanation:

The PERT method is a common method used to determine the weighted mean or average of three different values of a parameter to calculate a final estimate. Therefore, in the question shown above, the PERT duration can be estimated as:

PERT duration = (20+4*40+50) / 6 = (20+160+50) / 6 = 38.33 days.

Thus, for the given activity, the PERT duration is approximately 38.33 days.
