The Königsberg bridge problem asks if the seven bridges of the city of Königsberg (picture attached), over the river Preger can all be traversed in a single trip without doubling back, with the additional requirement that the trip ends in the same place it began. Trace over each bridge ONLY ONCE WITH ONE CONTINUOUS STROKE. What is the area of mathematics used to solve the problem?
Suppose a company charges a premium of $150 per year for an insurance policy for storm damage to roofs. 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…
John Allen Paulos has pointed out a problem with massive, untargeted wiretaps. To illustrate the problem, he sup-poses that one out of every million Americans has terrorist ties. Furthermore, he supposes that the terrorist profile is 99% accu-rate, so that if a person has terrorist ties, the profile will pick them up 99% of the time, and if the person does not have ter-rorist ties, the profile will accidentally pick them up only 1% of the time. Given that the profile has picked up a person, what is the probability that the person actually has terrorist ties? Dis-cuss how your answer affects your opinion on domestic wire-tapping.

1. 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?
Before 1918, approximately 60% of the wolves in a region were male, and 40% were female. However, cattled rachers in the area have made a determined effort to exterminate wolves. From 1918 present, approximately 65% of the wolves in the region are male, and 35% are female. Biologists suspect that male wolves are more likely than female to return to the area where the population have been greatly reduced. Round three decimals: a) Before 1918, in a ramdon sample 11 wolves spotted in the region, what is the probability that 8 or more were males? - what is the probability 8 or more were females? - what is the probability fewer than 5 were females? d) From the period 1918 to present in a ramdon sample 11wolves spotted in the region, what is the probability that 8 or more were males? -what is the probability 8 or more were females? -what is the probability fewer than 5 were females?
Suppose that an outbreak of cholera follows severe flooding in an isolated town of 3198 people. Initially (Day 0), 62 people are infected. Every day after, 15% of those still healthy fall ill. At the beginning of the first day (Day 1), how many people are still healthy? How many will fall ill during the first day? What is the total number of people infected after the first day
The process for cleaning up waste in a nuclear reactor core room eliminates 85% of the waste present in the area. If there is 1.7 kg of waste in the room at the beginning of the monitoring period and 2 kg of additionalwaste are generated each week, determine a recurrence relation and initial conditions describing the amount wn, of waste in the core room at the end of week n of the monitoring period.
3. It is thought that a larger proportion of urban voters, in contrast to rural voters, will support the governor in her bid for reelection. Random samples of 500 urban and 400 rural voters were selected. Three hundred urban voters plans to vote to reelect the governor and 200 rural voters plan to do so. At the 0.05 significance, does this demonstrate that a greater proportion of urban voters plan to vote to reelect the governor? State the assumptions associated with this procedure. please show how to solve it. no excel please
A professor has been teaching an undergraduate course for the last 15 years and has noticed that in the fall term there are more failures than in the same course offered in the winter term. The professor is wondering if this may be due to students being less prepared for the subject matter in the fall than in the winter because more students are taking the prerequisite simultaneously. Before drawing any conclusions though, the professor goes back over all the grades in all classes she taught in the last 15 years and counts the number of students that passed or failed. She then also records who had and had not completed the prerequisite first (see the table attached for data). On the basis of the last 15 years of data, should the 3 professor conclude that there is a difference in pass and failure rates depending on whether the prerequisite was done or not? Use the alpha of 0.05 and carry out all the steps of hypothesis testing to answer the hypothesis.
Within a group of 12 women, there are five who have known each other for a long time and have an excellent relationship. The other 7 women do not know the 5 friends nor do they know each other. Whenever a subset of the five friends is equal to or greater than 50% of the number of people in another work group (for example, if there are two of the five friends in the work group of three or four people), then the group work becomes high performance It is desired to form a working group by selecting five women from the 12 women. What is the probability that the work group is high performing? Please indicate your answer in the space provided below as a number between zero and one, to four decimal places.
Suppose that for a recent admissions class, an Ivy League college received 2,851 applications for early admission. Of this group, it admitted 1,033 students early rejected 854 outright, and deferred 964 to the regular admission pool for further consideration. In the past, this school has admitted 18% of the deferred early admission applicants during the regular admission process. Counting the students admitted early and the students admitted during the regular admission process, the total class size was 2,375. Let E, R, and D represent the events that a student who applies for early admission is admitted early, rejected outright, or deferred to the regular admissions pool. a. Use the data to estimate P(E), P(R), and P{D).b. Are events fand D mutually exclusive? Find P (E n D).c. For the 2,375 students who were admitted, what is the probability that a randomly selected student was accepted during early admission?d. Suppose a student applies for early admission. What is the probability…
