1.
Repeat problem 4.4 for a 5-level majority voting system.

2.
Compare the results of problem 4.4 with a single system: two elements  in parallel, two \  elements in standby.

3.
Compare the results of problem 4.5 with a single system: two elements  in parallel, two elements in standby.

4.
What should the reliability of the voter be if it increases the probability

of failure of the system of problem 4.4 by 10%?

5.
Compute the reliability at
t
c 1,000 hours of a system composed of a  series connection of module 1 and module 2, each with a constant failure  rate of l1 c 0.5 × 10−4 failures per hour. If we design a 3-level majority  voting system that votes on the outputs of module 2, we have the same  system as in problem 4.4. However, if we vote at the outputs of modules 1 and 2, we have an improved system. Compute the reliability of this  system and compare it with problem 4.4.
