Answer:

PERT is an estimating technique that uses a weighted average of three numbers (see below) to come up with a final estimate. The resulting PERT estimate is calculated as (O + 4M + P)/6. This is called a "weighted average" since the most likely estimate is weighted four times as much as the other two values.
