Question:

Using the following three-point estimates, estimate the expected value using the triangular distribution formula: Optimistic = 25, Pessimistic = 50, Most Likely = 35.

A 37
explanation

Expected value can be calculated using a triangular distribution (simple average) or beta distribution (weighted average). The three-point estimating formula that uses a triangular distribution is as follows: (Optimistic + Pessimistic + Most Likely) ÷ 3. Plug in the values provided to calculate the following: ($25 + $50 + $35) ÷ 3 = $36.7, or 37 when rounded to the nearest whole number.
