 Puneet Kumar said: (Jun 14, 2016) 1) Most Likely time: Most frequently occur if the activity were repeated many times. 2) Pessimistic Time: The shortest possible time to complete the activity if everything is going right. 3) Optimistic Time: The longest possible time to complete the activity if everything is going wrong. Probabilistic time (Mean of the above three Times) is calculated by given formula.
