Expected Time Calculation:

Formula:
The expected time (TE) can be calculated using the formula:
TE = (O + 4M + P) / 6

Given Data:
Optimistic time (O) = 2 minutes
Most likely time (M) = 5 minutes
Pessimistic time (P) = 8 minutes

Calculation:
TE = (2 + 4(5) + 8) / 6
TE = (2 + 20 + 8) / 6
TE = 30 / 6
TE = 5 minutes

Therefore, the expected time for the activity is 5 minutes.
