Q3. Reliability of component A is defined as (1 - PA) where p is the probability of failure of component A. So if p = 5% then R = 95% or 0.95. When you combine multiple components in series, a failure of any component will make the whole system fail. A system has 5 components in series R2 = 0.98; R2 = 0.97; R3 = 0.96; R4 = 0.95; R = 0.90 What is the system reliability a. 4.76 b. 0.952 c. 0.780 d. 0.900
