Problema Solution
A University Web server has five main components each with the same reliability. All five components must work for the server to function as intended. If the University wants to have a 95 percent reliability, what must be the reliability of each of the components? (Round answer to 4 decimal places, e.g. 15.2500)
Answer provided by our tutors
R = individual system component's reliability
Since there are 5 systems and the total system reliability is 95% we have
R * R * R * R * R = 0.95
OR, simply
R^5 = 0.95
.........
R = 0.9898
In other words, each component must have reliability of 0.9898.
