A newly designed robot vacuum has three major components. Components' reliabilities are .99, .98, and .95. All components must function in order for the robot to operate effectively.

A. It is now recommended that all three components be backuped independently, what is the reliability of the robot? (Please keep 3 digits after the decimal point.)

B. It is now recommended that the whole system have an identical backuped, (an exactly same system as backup), what will the reliability of the robot be? (Please keep 3 digits after the decimal point.)
