Free PMI Project Management Professional Practice Question

The correct answer is 7 days. This is calculated using the PERT formula for Expected Duration (TE): TE = (Optimistic + 4 x Most Likely + Pessimistic) / 6. Plugging in the values from the question, we get: TE = (4 + 4 x 6 + 14) / 6 = (4 + 24 + 14) / 6 = 42 / 6 = 7 days. This formula gives more weight to the most likely estimate while still considering the optimistic and pessimistic scenarios, providing a balanced estimate for project planning.
