In airline applications, failure of a component can result in catastrophe. As a result, many airline components utilize something called triple modular redundancy. This means that a critical component has two backup components that may be utilized should the initial component fail. Suppose a certain critical airline component has a probability of failure of 0.041 and the system that utilizes the component is part of a triple modular redundancy. (a) What is the probability that the system does not fail? (b) Engineers decide to the probability of failure is too high for this system. Use trial and error to determine the minimum number of components that should be included in the system to result in a system that has greater than a 0.99999999 probability of not failing.

Kaya claims that 8n is the number of dots in figure n. Kiana claims that the number of dots in figure n is given by 2(n+1)[tex]^{2}^-2(n--1)^{2}[/tex]Consider the square arrangements below in relation to the girls' expressions, where n represents the figure number. Determine whether Kaya, Kiana or both girls are correct in their given expressions. Justify your response.The evaluation of your response will be based on the following criteria.Correctly identifying which girl is correct in their given expressions while showing your work. Explaining your reasoning. Answer the question in two to three sentences.HINT: Plug in each figure number for n in both girl's expressions

A class is conducting an experiment using a die. Each person rolls the die 6 times and charts their results. If the results arecombined into a class list, which statement would be most correct?A.Every student has the same probability of getting each individual number.B.There is more of a chance a student will get all 6 numbers in their rolls than won'tC. Each individual student's data will match the theoretical data.D.An individual's experimental data should be closer to the theoretical probabilities than the combined experimental data ofthe class.

The probability distribution for damage claims paid by the Newton Automobile Insurance Company on collision insurance follows. Payment ($) Probability 0 0.85 500 0.04 1,000 0.04 3,000 0.03 5,000 0.02 8,000 0.01 10,000 0.01 (a) Use the expected collision payment to determine the collision insurance premium that would enable the company to break even. If required, round your answers to two decimal places. If your answer is zero, enter "0". x f(x) xf(x) 0 500 1000 3000 5000 8000 10000 Total (b) The insurance company charges an annual rate of $520 for the collision coverage. What is the expected value of the collision policy for a policyholder? (Hint: It is the expected payments from the company minus the cost of coverage.) If required, enter negative value as negative number. $ Why does the policyholder purchase a collision policy with this expected value? The input in the box below will not be graded, but may be reviewed and considered by your instructor.

9. A judge hears the following arguments in a murder hearing. The DNA test that places the accused at the murder scene has a true positive rate of 90% (i.e. the probability that the test returning positive given that the accused was actually present at the scene is 0.9). Similarly, the DNA test has a false negative rate of 80% (i.e. the probability that the test returns negative given that the accused was not present at the scene is 0.8). Everyone in the town has a equal probability of being at the murder scene, and the town has a population of 10,000. Given the fact that the DNA test returned a positive result for the accused, what is the probability that the accused was at the murder scene?
