4) Suppose there is a medical screening procedure for a specific cancer that has sensitivity =90, and specificity = .95. Suppose the underlying rate of the cancer in the population is001. Let B be the event "the person has that specific cancer," and let A be the event "thescreening procedure gives a positive result.(a) What is the probability that a person has the disease given the results of the screeningis positive?(b) Does this show that screening is effective in detecting this cancer?%3D

Given: Sensitivity = 0.90 Specificity = 0.95 cancer rate = 0.001 Let B be the event “the person has…

If the odds in favor of event E are a to b the probability of the event is given by P(E) = a/(a+b) Choose one of the causes of death from the article and convert odds to probability - determine the probability of this cause of death. Determine the probability that the cause of death is not the one you chose. Explain why it is so difficult to calculate this probability directly yet so easy to calculate it using a trick.You can chose which death or you can do for drowning doesnt matter.
