The readers and writers dilemma may be posed in a number of different ways, depending on the order in which different categories of activities might be initiated. Outline three distinct permutations of the issue, each of which favors (or does not favor) a different set of methods. The actions to take upon a reader's or writer's readiness to access the database and at the completion of a procedure need to be detailed for each variant.
Suppose a survey was done in three states on the Covid-19 pandemic situation. Of the total population of the three states, 25% live in state X, 45% live in state Y, and 30% live in state Z. In state X, 20% of the citizens have been infected with Covid-19, in state B, 10% of the citizens have been infected with Covid-19, and in state C, 15% of the citizens have been infected with Covid-19. Let X represents the event that the citizen is from state X, Y represents the event that the citizen is from state Y and Z represents the event that the citizen is from state Z. Let C represents the event that the citizen has been infected with Covid-19. a) Find the probability that a randomly selected citizen has not been infected with Covid-19 and lives in state X and find the probability that a randomly selected citizen has been infected with Covid-19 and Given that a randomly selected citizen has been infected with Covid-19, find the probability that the selected citizen is from state Y.

Queen Mutuashi, a medical researcher at a famous hospital in Mombasa is interested infinding the causes of lung cancer in Kenya. In an attempt to achieve her objective, shesurveyed 450 lung cancer patients in the hospital and found out that 140 were cigarettesmokers, 164 lived in urban areas, and 200 had hazardous occupations. 80 of the smokerslived in urban areas, 56 had hazardous occupations, and 33 were in both categories. 60 ofthe patients with hazardous occupations neither lived in an urban area nor smoked.Required(i) Represent the information on a Venn diagram(ii) Determine the number of patients living in urban areas who had hazardousoccupations.(iii) How many of the patients living in the urban areas neither smoked nor had hazardousoccupations?(iv) Determine the number of patients who smoke if and only if they lived in urban areas.(v) Queen Mutuashi would infer that these are the three common causes of lung cancer if70% of the individuals suffering from the disease have at…
With the urgency of trying to get so many individuals vaccinated against the Covid-19 virus, it is important to be able to offer clinics in places where most individuals can and want to be able to access clinics in their neighbourhoods. Unfortunately, costs of setting up clinics and running them are somewhat expensive. The county health unit in one particular county in Ontario is not only responsible for setting up and running these clinics, it is also responsible for any expenses involved with these clinics. The health unit in this county has identified 8 potential locations, the neighbourhoods (labelled 1 through 10) in the county that each location is most likely to attract potential individuals to get their vaccinations, and, the estimated total costs of setting up and running the clinics in each of these potential locations until the clinics are no longer needed there. The following table includes the potential locations (labelled A through H), the neighbourhoods in the county…
write out your observations and comments regarding the comparison of confirmed cases of COVID-19 and economic development among swing, solid blue, and solid red states. For example, do swing states, on average, have more (or less) confirmed cases of COVID-19 and better (or worse) economic development than solid red and solid blue states? Are these observations or findings attractive to you? How would you explain these observations or findings?

In a California study, Dean Lester Breslow and Dr. James Enstrom of the University of California at Los Angeles' School of Public Health concluded that by following 7 simple health rules a man's life can be extended by 11 yrs. on the average and a woman's life by seven. These 7 rules are: no smoking, regular exercise, use alcohol moderately, get seven to eight hours of sleep, maintain proper weight, eat breakfast, and do not eat between meals. In how many ways can a person adopt 5 of these rules to follow , if the person never drinks and always eats breakfast?
