Question
Assume that there is a 5% rate of disk drive failure in a year.
a. If all your computer data is stored on a hard disk drive with a copy stored on a second hard disk drive, what is the probability that during a year, you can avoid catastrophe with at least one working drive?
b. If copies of all your computer data are stored on
three independent hard disk drives, what is the probability that during a year, you can avoid catastrophe with at least one working drive?
a. With two hard disk drives, the probability that catastrophe can be avoided is
(Round to four decimal places as needed.)

- Suppose a doctor is conducting a clinical trial to test the effectiveness of a new drug for treating a certain disease. The doctor randomly assigns 200 patients to two groups: a treatment group that receives the new drug, and a control group that receives a placebo. If 30% of the patients in the treatment group experience a full recovery from the disease, and 20% of the patients in the control group experience a full recovery, what is the probability that the new drug is truly effective, given these results?arrow_forwardAn airline has a policy of booking as many as 18 persons on an airplane that can seat only 17. past studies have revealed that only 81% of the booked passengers actually arrive for the flight. find the probability that if the airline books 18 persons not enough seats will be available.arrow_forwardThe principle of redundancy is used when system reliability is improved through redundant or backup components. Assume that a student's alarm clock has a 5.6% 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? 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? c. What is the probability of not being awakened if the student uses three independent alarm clocks? d. Do the second and third alarm clocks result in greatly improved reliability? A. No, because the malfunction of both is equally or more likely than the malfunction of one. B. No, because total malfunction would still not be unlikely. C. Yes, because total malfunction would not be impossible, but it would be unlikely. D. Yes, because you can always be certain that at…arrow_forward
- In a population of 10,000, there are 5000 nonsmokers, 2500 smokers of one pack or less per day, and 2500 smokers of more than one pack per day. During any month, there is a 5% probability that a nonsmoker will begin smoking a pack or less per day, and a 4% probability that a nonsmoker will begin smoking more than a pack per day. For smokers who smoke a pack or less per day, there is a 10% probability of quitting and a 10% probability of increasing to more than a pack per day. For smokers who smoke more than a pack per day, there is a 9% probability of quitting and a 10% probability of dropping to a pack or less per day. How many people will be in each group in 1 month, in 2 months, and in 1 year? (Round your answers to the nearest whole number.)(a) in 1 month:nonsmokers:1 pack/day or less:more than 1 pack/day:(b) in 2 months:nonsmokers:1 pack/day or less:more than 1 pack/day:(c) in 1 year:nonsmokers:1 pack/day or less:more than 1 pack/day:arrow_forwardSuppose that it is known that 45% of eighteen-year-olds in a particular city do not have a driver's licence.
