Chapter 3.7, Problem 29E
Suppose that the space shuttle has three separate computer control systems: the main system and two backup duplicates of it. The first backup would monitor the main system and kick in if the main system failed. Similarly, the second backup would monitor the first. We can assume that the failure of one system is independent of the failure of another system, since the systems are separate. The probability of failure for any one system on any one mission is known to be 0.01.
a. Find the probability that the shuttle is left with no computer control system on a mission.
b. How many backup systems does the space shuttle need if the probability that the shuttle is left with no computer control system on a mission must be

A system consists of two components. The probability that the second component functions in a satisfactory manner during its design life is 0.9, the probability that at least one of the two components does so is 0.92, and the probability that both components do so is 0.85. Given that the first component functions in a satisfactory manner throughout its design life, what is the probability that the second one does also?
An average of 100 customers per hour arrive at GothamCity Bank. It takes a teller an average of 2 minutes to servea customer. Interarrival and service times are exponential.The bank currently has four tellers working. The bankmanager wants to compare the following two systems withregard to average number of customers present in the bankand the probability that a customer will spend more than 8minutes in the bank:System 1 Each teller has her own line, and no jockeyingbetween lines is permitted.System 2 All customers wait in a single line for the firstavailable teller.If you were the bank manager, which system would youprefer?
On a certain hole, a golfer knows that he has a 70% chance of reaching the green (putting surface) in one stroke, 20% in two strokes, 8% in three, and 2% in four or more. If he reaches the green on his first stroke, he has an 80% chance of putting the golf ball in the cup on his second stroke. If he does not reach the green on his first stroke, then he has a 30% chance of putting the golf ball in the cup on his second stroke. What is the probability that the golfer will reach the green in one stroke and put the ball in the cup on his second stroke?

- Consider two types of home insurance: theft insurance and carthquake insurance. Each year there is a 1% chance that the home will be robbed and a 1% chance that the home will be damaged by an canhquake. Suppose an insurance company writes 100,000 policies of each type for homeowners. The risk of earthquake is a type of common risk, while the risk of theft is independent across households. At the beginning of the year, the homeowner expects 1% chance of placing a claim for either type of insurance. However, at the end of the year, the homeowner will have either filled a claim (100%) or not (0%). The standard deviation (expressed in percentage terms) of the claim for an individual homeowner in case of earthquake is kype your answer The standard deviation (expressed in percentage terms) of the claim for an individual homeowner in case of theft is type your answer.

The study uses 10 volunteers who claim to suffer from migraines. Half of the volunteers are randomly assigned to use treatment A when they experience their first migraine. The other half are assigned to use treatment B. Then, after no treatment for one month, the treatments are reversed. The volunteers each record the amount of time it takes, in minutes, to experience relief from their migraine under each treatment. The data are displayed in the table. The conditions for inference are met. The 99% confidence interval for the mean difference (A – B) in the time it takes to experience relief is –8.37 minutes to 0.732 minutes. What is the correct interpretation of this interval? The researchers can be 99% confident that the interval from –8.37 minutes to 0.732 minutes captures the true mean time it takes to experience relief.

It takes a teller an average of two minutes to serve a customer. Interarrival and service times are exponentially distributed. The bank currently has four tellers working. The bank manager wants to compare the following two systems with regard to the average number of customers present in the bank and the probability that a customer will spend more than eight minutes in line. System 1: Each teller has his or her own line (and no moving between lines is permitted). Arriving customers are equally likely to choose any teller. System 2: All customers wait in a single line for the first available teller. Help the bank manager reach a decision by filling the following table. If needed, round your answers to one decimal digit. Average number of customers Prob (wait > 8') System 1 ________________________________________ % System 2 _________________________________________%arrow_forwardAssume the chances of failure of each component is given in Figure.

- Consider a production system composed of two machines, where only one machine needs to be operational at any given time. The breakdown probability of any operational machine on any given day is 0.2. In case of a machine failure, the production is stopped for the day, and is resumed the next day with the other machine (if available). The repair job of the failed machine also starts the next day. It takes two days to repair a machine, and both machines can be repaired simultaneously.1) Define the state space and draw the state transition diagram.2) Starting with two available machines at the beginning of the first day, what is the probability that both machines are unavailable at the end of the 3rd day?3) In the long run, what is the ratio of the days that both machines are unavailable?arrow_forwardA system contains two components, A and B. The system will function only if both components function. The probability that A functions is 0.98, the probability that B functions is 0.95, and the probability that either A or B functions is 0.99. What is the probability that the system functions?arrow_forwardConsider a system that functions whenever at least five of its seven components work. Suppose that each component works independently with probability 1/4. Find the probability that the system will function. Find the probability that only five components work given that the system is functioning. Find the probability that Component 3 works given that the system is functioning.arrow_forward
- A system consists of two components. The probability that the second component functions in a satisfactorymanner during its design life is 0.9, the probability that at least one of the two components does so is 0.96,and the probability that both components do so is 0.75. Given that the first component functions ina satisfactory manner throughout its design life, what is the probability that the second one does also?arrow_forwardA seamstress works exclusively on one stage of the process of a special garment design. This phase requires exactly half an hour to finish the garment. Every 30 minutes an assistant arrives at the seamstress's table to collect those finished garments and deliver those that require the process (unprocessed garments).The number of raw garments brought by the assistant to the seamstress is uncertain; 30% of the occasions arrive without garments; 50% of the time he wears one garment and 20% of the time he wears 2 garments. The assistant is instructed that there are never more than three unprocessed garments left on the seamstress's table (those that cannot be left are taken to another seamstress). Determine the transition graph and matrix that models the number of raw garments on the seamstress's table just before the assistant arrives.arrow_forwardIn a certain four-engine vintage aircraft, now quite unreliable, each engine has a 15% chance of failure on any flight, as long as it is carrying its one-fourth share of the load. But if one engine fails, then the chance of failure increases to 30% for each of the other three engines. And if a second engine fails, each of the remaining two has a 45% chance of failure. Assuming that no two engines ever fail simultaneously, and that the aircraft can continue flying with as few as two operating engines, find the probability for no engine failures.arrow_forward
