Certified Associate in Project Management (CAPM) — Question 489

The project manager has the following information about the estimated duration for an activity:
✑ Most likely [tM] `" 15 days
✑ Pessimistic [tP] `" 20 days
✑ Optimistic [tO] `" 10 days
What is the estimated duration of this activity, according to the triangular distribution technique?

Answer options

Correct answer: B

Explanation

The triangular distribution formula for estimating the duration is (tO + tM + tP) / 3. Plugging in the values gives (10 + 15 + 20) / 3 = 15 days, which is the correct answer. The other options do not represent an average calculation based on the provided optimistic, most likely, and pessimistic durations.
