Question

System reliability improves by using redundant systems. The reliability of the system can be improved by using two such systems in parallel. Again, if the probability of failure of any one subsystem is 0.01, what is the reliability of this system?

Answer 1

Answer:

Reliability is 0.99

Explanation:

Reliability is complementary to probability of failure, i.e. R(t) = 1 –F(t)

F(t) = 0.01

R(t) = 1 - 0.01 = 0.99

Reliability is 0.99

Its means that the probability of failure has dropped 10 times.
