a)You have two components working in parallel (i.e. one is a backup to the other). One has a reliability of 0.55 and the other has a reliability of 0.60. What is the reliability of this part of the whole system?

b)You have three components working in parallel (i.e. two are backups to the first). They have reliabilities of 0.55, 0.65, and 0.65. What is the reliability of this part of the whole system?

c)You have four components in a system with two working in parallel (i.e. one is a backup to the other) and the other two in sequence to the first two (the top of the system in the questions. The first two have reliabilities of 0.55 and 0.6 and the next two have reliabilities of 0.87 and 0.94. What is the reliability of this part of the whole system?

d)A system for milling 2x6s has four sensitive components connected in series with reliabilities of 0.92, 0.72, 0.84 and 0.85. What is the reliability of this original system?
