I have two homework to do please, and these are its details
1. Read Chapter 11 (pp. 303-317) in Charles Yoe, Principles of Risk Analysis to review probability analysis. Read Chapter 3 (pp. 113-146) in Damon Coppola, Introduction to International Disaster Management to review the concept of risk. 2. A truck driver earns ,000 each day by driving fruits and vegetables from rural farms to a city. 10% of the time he faces such natural hazards as rain, hail, heavy winds, and dust storms. When subject to such natural hazards, there is a 30% chance that he will get into an accident. When he gets into an accident, there is a 60% chance that his truck and/or the fruits and vegetables will suffer a loss of $100,000 and the repairs will take 2 days to complete. There is a 30% chance that he will have to pay $200,000 and 4 days of losses, and a 10% chance he will have to pay $300,000 and 5 days of losses. What is risk the driver assumes when driving under hazardous conditions and is this risk worth taking? 3. A fire breaks out in a hotel that has 50 rooms that rents for $100/day, and has an average occupancy rate of 90%. The average variable cost of operating the hotel is $60 a rented room/day. The hotel is open 365 days/year. There is a 70% chance that the fire is minor and will cause the hotel to shut down for 2 months for repairs, but a 30% the fire is significant and will cause the hotel to shut down for 6 months for repairs. Assume the mortgage payment for the hotel during this time period is $25,000 per month. What is the total risk of the fire for this hotel? 4. A power plant faces the threat of significant damage from flooding due to heavy rainfall. Significant flooding occurs once every 5 years. Such flooding will inflict $100,000 in damage to the property outside of the flood walls surrounding the power plant. There is a 20% chance the flood walls will fail. Should that happen, it will inflict $200,000 in damage to the property within the facility that lies outside the electrical generation building. Within this building, the water will cause $300,000 worth of damage whether or not the building pumps work. There is a 10% chance that the building pumps will fail. When this happens the plant must engage in shutting down the generation of electricity. There is a 60% chance of a safe shutdown, which will cost $200,000, but a 40% chance of an unsafe shutdown, which will cost $800,000. Also, when the plant shuts down safely, it takes one week to restart. When the plant shuts down unsafely, it takes one month to restart. The plant’s average variable cost of producing electricity is $80,000 per day, and generates sales worth $130,000 per day. What is the total risk facing this power plant from heavy rain fall?

Questions:
Analyze numerically the two networks below in Fig. 1 and Fig. 2 to determine whether they are random or scale-free networks.
Determine which networks below will endure substantial loss when subject to the targeted attack of two nodes? Which networks will endure substantial loss when subject to the failure of two random nodes?
Conduct an internet search on the fresh water networks of Saudi Arabia. Analyze this system and explain vulnerability to both random accidental failures and intentional military or terrorist attacks.
