2 Mouldy home. A landlord is deciding whether to undertake routine maintenance on their rental property to reduce the potential for damp/mould issues. The weather throughout the year could turn out to be mostly dry, moderately wet, or extremely wet. Without routine maintenance, the cost of damage to the property and lost rental income is $500 in a mostly dry year, $2000 in a moderately wet year, and $8000 in an extremely wet year. Routine maintenance will cost $1200 and reduces the cost of damages and lost income to $0 in a mostly dry year, $400 in a moderately wet year, and $2400 in an extremely wet year. (a) Construct the payoff table for this decision which describes the total costs. (b) Calculate the EMVS for the two decisions ("No Maintenance", "Maintenance") if the probabilities of mostly dry, moderately wet and extremely wet are 0.25, 0.6 and 0.15, respectively. (c) What would be a sensible objective in this scenario and, based on your calculations, what should the landlord do?

more than one option is the answer. So what else could it also be along with option c?

3. A shop owner blends a fancy brand of tea with a cheaper brand. The fancy brand sells for $5 per pound, and the cheaper brand sells for $2 per pound.
