It is known that the frequency of a database server experiencing a Poisson distributed error with an average of 2 times a week. a. What is the probability that in two weeks there will be three errors? b. What is the probability that after one day a database error occurs, the next error will occur less than four days later? c. It is known that on the third day there is not a single error, what is the probability that on the fifth day there is still no error?

The principle of redundancy is used when system reliability is improved through redundant or backup components. Assume that a student's alarm clock has a 16.5% daily failure rate. a. What is the probability that the student's alarm clock will not work on the morning of an important final exam? (Round to three decimal places as needed.) b. If the student has two such alarm clocks, what is the probability that they both fail on the morning of an important final exam? (Round to five decimal places as needed.) c. What is the probability of not being awakened if the student uses three independent alarm clocks? (Round to five decimal places as needed.)
A rare type of HPV virus affects 1% of the population in a state. A new test is designed to detect the virus before an outward manifestation. If given to an infected person the test shows positive result 97% of the time. If given to an uninfected person the test shows positive (false) result 2% of the time. (Use a probability tree) If the test is given to a randomly chosen person in the population and gives a positive result, what is the probability that the person is actually infected?
As a manager of an organization, what probability distribution from this week binomial/poisson would you use if you wanted to estimate your annual employee turnover? My company has 550 employees and we lose 15 employees every 2 months.
The principle of redundancy is used when system reliability is improved through redundant or backup components. Assume that a student's alarm clock has a 15.7% daily failure rate. Complete parts (a) through (d) below. a. What is the probability that the student's alarm clock will not work on the morning of an important final exam? | (Round to three decimal places as needed.) b. If the student has two such alarm clocks, what is the probability that they both fail on the morning of an important final exam? (Round to five decimal places as needed.) c. What is the probability of not being awakened if the student uses three independent alarm clocks? (Round to five decimal places as needed.) d. Do the second and third alarm clocks result in greatly improved reliability? O A. No, because total malfunction would still not be unlikely. O B. No, because the malfunction of both is equally or more likely than the malfunction of one. OC. Yes, because you can always be certain that at least one…
