If the most optimistic and pessimistic times for a task are 3 and 11 days respectively,then the variance for the duration of the activity ______.
A)= (3 - 11)/ 6)raised to 2
B)= (11 - 3)/ 6)raised to 2
C)= (11 - 3)/ 3)raised to 2
D)= (3 - 11)/ 3)raised to 2

Variance for the duration of the activity can be calculated using the formula: Variance = [(pessimistic time - optimistic time) / 6]^2
Substituting the given values, we get:
Variance = [(11-3)/6]^2 = (8/6)^2 = (4/3)^2 = 16/9
Therefore, the variance for the duration of the activity is (11 - 3)/ 6)raised to 2 which is option B.
