Answer: c. $5,750
Step-by-step explanation:
Expected value will be the weighted average of the payoffs of the different scenarios.
= Base fee + Addition if finished 1 week early + Addition if finished 2 weeks early + No addition
= 5,000 + ( 5,000 * 10% * 60%) + ( 5,000 * 30% * 30%) + (5,000 * 0% * 10%)
= $5,750
