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 12.2% daily failure rate. Complete parts (a) through (d) below. C a. What is the probability that the student's alarm clock will not work on the morning of an important final exam?

You are the manager of a manufacturing plant and you are responsible for quality control. Each day, a random sample of 10 items is selected from the production line and tested by a quality control technician. A item can be in good condition or defective, and the probability that an item is defective is 0.05. You know by experience that the technician records the result of the test on an item correctly 80% of the time. Let X be the number of items that were recorded as defective by the technician (in the sample of 10 tested items). (a) Find the probability P(X= 1). (b) If the technician recorded one defective item in the sample, what is the conditional probability that there was no defective item in the sample?

To generate leads for new business, Gustin Investment Services offers free financial planning seminars at major hotels in Southwest Florida. Gustin conducts seminars for groups of 25 individuals. Each seminar costs Gustin $3,400, and the commission for each new account opened is $4,900. Gustin estimates that for each individual attending the seminar, there is a 0.01 probability that he/she will open a new account.   Determine the equation for computing Gustin's profit per seminar, given static values of the relevant parameters.   Profit =(New accounts opened x _______)-_________   Construct a simulation model to analyze the profitability of Gustin's seminars. Would you recommend that Gustin continue running the seminars? (Use at least 1,000 trials. Round your answer to two decimal places.)   What is the minimum number of attendees (in a multiple of five, i.e., 25, 30, 35, …) that Gustin needs before a seminar's average profit is greater than zero? =______ attendees

George is a big fan of music from the 1960s, and 22% of the songs on his iPod are Beatles songs. Suppose George sets his iPod to  "shuffle," so that it selects songs randomly (assume the shuffle function permits repetition of songs). During a long drive, George plays 50 randomly selected songs. Calculate the probability that more than 30% of the 50 randomly selected songs are Beatles songs. Round your answer to four decimal places.

The mean percent of childhood asthma prevalence in 43 cities is 2.21​%. A random sample of 30 of these cities is selected. What is the probability that the mean childhood asthma prevalence for the sample is greater than 2.5​%? Interpret this probability. Assume that σ=1.22​%.

Oxnard petri Ltd is buying hurricane insurance for it's off-coast drilling platform. During the next five years, the probability of total loss of only the above-water superstructure ($250 million) is .25, the probability of total loss of the facility ($950 million) is.25, and the probability of no loss is.50. Find the expected loss.( Input the amount as a positive value.) Expected Loss is what?

File Edit View History O Part: 0/2 Insurance: An insurance company sells a 1-year term life insurance policy to an 81-year-old man. The man pays a premium of $3900. If he dies within 1 year, the company will pay $62,000 to his beneficiary. According to the U.S. Centers for Disease Control and Prevention, the probability that an 81-year-old man will be alive 1 year later is 0.9381. Let X be the profit made by the insurance company.
