1. The construction time for a bridge depends on the weather. The project is expected to take 250 days if the weather is dry and hot. If the weather is damp and cool, the project is expected to take 350 days. Otherwise it is expected to take 300 days. Historical data suggest that the probability of cool damp weather is 30% and that of hot dry weather is 20%. What is the expected completion time for the project?

2. What is the greatest present worth of the path through that diagram to the nearest dollar?
