For a system composed of 10 interdependent components that each have individual reliability of .99, the overall system reliability is:
A) .40
B) .60
C) .90
D) .99

Question

Quizplus · Accepted Answer

The overall system reliability can be calculated using the formula: Roverall = R1 x R2 x R3 x ... x Rn, where R1 through Rn represent the individual reliabilities of the components. 
Therefore, Roverall = (.99)^10 = .904, which is approximately equal to .90. Hence, the correct answer is option C) .90.
