Step 2 − For each task, find three values − most optimistic estimate (O), a most likely estimate (M), and a pessimistic estimate (L). This is not an application for financial aid, and the actual net price of your education may vary. Definition: If the estimate is acquired as a single number, then the estimate is called as a point estimate. Estimating operations on proper fractions in this way is sometimes more accurately done by a human than a calculator.
