The variance of the duration of an activity in project management is calculated using the formula: variance = ((Pessimistic time - Optimistic time) / 6)^2. Substituting the given values: variance = ((9 - 7) / 6)^2 = (2 / 6)^2 = (1/3)^2 = 1/9 = 0.11.

The Most Pessimistic Time for a Task Is 9 Months
