(e) The renovation above can be performed via one of two methods (Method A and Method B). Method A has a base cost of $650,000 (assuming no delay), Method B has a base cost of $660,000 (assuming no delay). Method A has a 75% chance of being completed on time. IF there is a delay in Method A, there is a 40% chance it will be a one day delay, a 40% chance it will be a two day delay and a 20% chance it will be a three day delay. The cost per day for a delay for Method A is $50,000. Method B has an 85% chance of being completed on time. IF there is a delay in Method B, there is a 60% chance it will be a one day delay, a 25% chance it will be a two day delay and a 15% chance it will be a three day delay. The cost per day for a delay for Method B is $40,000. Using a decision tree, which Method would you use to perform the renovation
