Answer:

Pert Estimate = 6.83

Explanation:

The PERT duration is calculated using the following formula

Pert Estimate = (Optimistic + (4 X Most Likely) + Pessimistic)/6

In this scenario, the most optimistic amount of time would be 5 days for completion. The most likely or average amount of time this type of project takes is 7 days, and if things go wrong the most pessimistic outlook is 8 days. Therefore we can plug these values into the formula and calculate the PERT duration.

Pert Estimate = (5 + (4 * 7) + 8)/6

Pert Estimate = (5 + (28) + 8)/6

Pert Estimate = 41/6

Pert Estimate = 6.83
