A product has three components, A, B, and C, with reliabilities of 0.95, 0.98, and 0.995. Engineers intend to put a redundant component A that has reliability 0.70. With this change, system reliability will
A) fall by 20%.
B) fall by 10% or less.
C) rise.
D) cannot determine from the information provided.
E) none of the above.
Redundant Component
A component in a system that is not essential for immediate function but serves as a backup to increase reliability.
System Reliability
The probability that a system will perform its required functions without failure under stated conditions for a specified period of time.
- Understand the method for determining system reliability from the reliability of its components and the configuration of the system.

Final Answer :
C
Explanation :
The system reliability increases with the addition of a redundant component A, even with a lower reliability of 0.70, because it provides an additional path for success, thus enhancing the overall system reliability.
