Actuarial studies show that in case of a storm, the insurance company will pay out an average of $8000 for damage to a composition shingle roof and an average of $12,000 for damage to a shake roof. They also determine that out of every 10,000 policies, there are 7 claims per year made on composition shingle roofs and 11 claims per year made on shake roofs. What is the company’s expected value (i.e., expected profit) per year of a storm insurance policy? What annual profit can the company expect if it issues 1000 such policies? Determine the probability of a composition shingle roof claim out of 10,000 = ______ Determine the probability of a shake roof claim out of 10,000 = ______ How many claims are made out of 10,000? = _______ What is the probability of no claims out of 10,000? = _______ How much does each shingle roof claim cost the company, don’t forget each person pays $150…If the national economy shrank at an annual rate of 6% per year for three consecutive years, then the economy shrank by 18% over the three-year period.

- In winter of a country, it rains 45% of the days and shine 55% of the days. Mr. X has abarometer which wrongly predicts 5% of the time in rainy days and 10% on shiny days.Mr. X does not carry umbrella if barometer predicts shine. On good shiny morning inwinter, his barometer predicts “shine” and he does not carry umbrella. What is theprobability that Mr. X will suffer from rain on that day.A company is considering a project which has three options. The payoffs are shown in the body of thetable. In this instance, the payoffs are in terms of present values, which represent equivalent currentdollar values of expected future income less costs. This is a convenient measure because it places allalternatives on a comparable basis. If a small facility is built, the payoff will be the same for all threepossible states of nature. For a medium facility, low demand will have a present value of $7 million,whereas both moderate and high demand will have present values of $12 million. A large facility willhave a loss of $4 million if demand is low, a present value of $2 million if demand is moderate,and a present value of $16 million if demand is high.The payoff table depicting revenues and is shown in the following table. (a) Which alternative should the manager choose under the maximax criterion? (b) Which option should the manager choose under the maximin criterion? (c) Which option…An Internet advertising agency is studying the number of "hits" on a certain web site during an advertising campaign.

- A project requires an initial outlay of $92000 and produces a return of $30000 at the end of year 1, $40000 at the end of year 2, and $42xyz at the end of year 3, where x, y, z are the last three digits of your student code (for example: if a student code is 17071365 then x = 3, y = 6, z = 5 and $42xyz=$42365). a/ Use the trial-and-error method or another appropriate method to determine the internal rate of return IRRof the project (express IRR in percentage, rounded to one decimal place); b/ Find the net present value NPV of the project if the market rate r is equal to the value of IRR as found above, then give a comment.Due to the high incidence of crime, a company is giving its employees new and secured access to the company. Instead of leaving the doors open, they are installing a card system. To open the door, employees must insert a card into a slot. If a green light comes on, it is okay to turn the handle and open the door; if a yellow light comes on it indicates the door is locked from inside and you cannot enter. Suppose that 90% of the time when the card is inserted, the door should open because it is not locked from the inside. When the door should open, the system makes errors 2% of the time. That is, the green light will appear 98% of the time. When the door should not open, the system makes errors 5% of the time (green light appears). Suppose you inserted the card, and the light is green, what is the probability the door will open?If the alleles A and B of the cystic fibrosis gene occur in a population with frequencies p and 1 - p (where pis between 0 and 1), then the frequency of heterozygous carriers (carriers with both alleles) is 2p(l - p). Which value of p gives the largest frequency of heterozygous carriers?
- jessie Lim is definitely considering buying a private apartment near her parents’ house. She is interested in a 3-room unit priced at $1.8 million now. However, the current turbulence in global economy due to the outbreak of COVID-19 makes her hesitate on whether to buy it now or one year later. Singapore property market currently is still having an upward momentum despite the current situation. There is p% chance that such momentum will continue, where p is a value between 0 and 100, and the property price will increase by 15% one year later, but there is also (100-p)% chance that the market will turn negative and drop by 20% one year later. (In the following questions, we assume the money is all considered at its present value. No other factors such as loss of opportunity are taken into consideration.)

By the end of the season, an estimated total of 49 million people in the United States had contracted the flu, of whom an estimated 79,000 died from the flu. Assume that the US population was 300,000,000 during the 2019-2020 flu season and that during the season, a total of 2.9 million Americans died from all causes (including the flu). Assume the population of the US remained the same at the midpoint of the season. Report mortality rates per 100,000. Be sure to express the measure in the correct format. a.What was the proportionate mortality rate from flu during the 2019-2020 flu season? b.What was the case fatality rate from flue during the 2019-2020 flu season?
