Answer:
b. calculate the expected time, using (a 4m b)/6.
Explanation:
In project management, when activity times are uncertain, the appropriate approach is to calculate the expected time using the following expression:
Where 'a' is the most optimistic outcome, 'm' is the most likely time, and 'b' is the most pessimistic outcome.
Therefore, the answer is b. calculate the expected time, using (a 4m b)/6.
