A system consisting of two identical components A& B. (a) Under what conditions does the system fail? (b) Ifthe reliability (i.e. the ability of the system to perform itsintended function satisfactorily) of components A & B are90% and 80%, respectively, under what conditions does thesystem fail?
The Beta II computer's electronic processing unitcontains 50 components in series. The average reliability of eachcomponent is 99.0%. Using F igure 17.2, determine the overallreliability of the processing unit
One of the solar instruments on a satellite has three major parts, all of which must operate. Two have reliabilities of .7 and the other has a reliability of .9. In case the system fails, there is an identical backup system that kicks on automatically. The overall reliability of the system, including the backup, is closest to:

- Rick Wing, salesperson for Wave SolderingSystems, Inc. (WSSI), has provided you with a proposal forimproving the temperature control on your present machine.The machine uses a hot-air knife to cleanly remove excess solder from printed circuit boards; this is a great concept, butthe hot-air temperature control lacks reliability. According toWing, engineers at WSSI have improved the reliability of thecritical temperature controls. The new system still has the foursensitive integrated circuits controlling the temperature, butthe new machine has a backup for each. The four integratedcircuits have reliabilities of .90, .92, .94, and .96. The fourbackup circuits all have a reliability of .90.a) What is the reliability of the new temperature controller?b) If you pay a premium, Wing says he can improve all fourof the backup units to .93.
