Quizplus · Accepted Answer

PERT uses a weighted average of the most optimistic time, most pessimistic time, and four times the most likely time to calculate the expected time. This formula takes into account both the best and worst case scenarios, as well as the most likely scenario, to arrive at a more accurate estimate of the expected time.
