30% probability that the development may be simpler than expected, savings $2,500.

5% probability of a design defect causing $5,000 of rework.

.Calculate the net expected value for the project risks and opportunities cited above.

.How much should you plan for your contingency reserve budget based on the above?

How much would you allocate for the management reserve?
