Answer:

d.9975

Explanation:

The computation of the reliability of the appliance in the case when the backup QK were added is shown below:

= ( 1 - QK's reliability) × QK's reliability + QK's reliability

= (1 - 0.95) × 0.95 + 0.95

= 0.05 × 0.95 + 0.95

= 0.0475 + 0.95

= 0.9975

Hence, the correct option is d. 0.9975

The same is to be considered

Also we simply applied the above formula so that the correct percentage could come
