A computer server is dependent on a component that is critical to its operation. This component, a module A, has a reliability of 60% (=0.6). To increase the reliability of the server, you are considering adding an extra module A as a backup, which has the same reliability of 60% as the module A. The server functions properly if at least one of the two modules (modules A or A') works properly. There is no correlation between two modules A and A. In other words, two modules are independent.

What is the probability that the server fails? What is the reliability of the server?

A

0.01 (=1%)

B

D

0.16 (=16%)

E
