Calculation of Probable Range
- To calculate the probable range of completion time, we use the formula:
Probable time = (Optimistic + 4*Most Likely + Pessimistic) / 6

Given data:
- Optimistic time = 8 weeks
- Most Likely time = 15 weeks
- Pessimistic time = 18 weeks

Calculation:
Probable time = (8 + 4*15 + 18) / 6
Probable time = (8 + 60 + 18) / 6
Probable time = 86 / 6
Probable time = 14.33 weeks
Therefore, the probable range of completion time of the activity is from 9.32 to 19.34 weeks, which is option 'C'.

The optimistic, most likely and pessimistic time estimates of activity...
Concept:
The expected completion time (tE)

Where,
t0 = optimistic time, tL = most likely time
tP = pessimistic time
The probable range is from (te - 3σ) to (te + 3σ)   
σ is Standard Deviation
Solution:
The expected completion time (tE)​

The Probable range of completion time of the activity will be from (t− 3σ) t o(t+ 3σ)
i.e. (14.33 - 3 × 1.67) to (14.33 + 3 × 1.67)
9.32 weeks to 19.34 weeks
