In a particular measurement system, two instruments with individual reliability of
0.80 are connected together in parallel.
(a) Calculate the reliability of the measurement system if it can continue to function as long as both of the instruments do not fail at the same time.
(b) How many instruments with this same individual reliability of 80% would have
to be connected together in parallel to achieve an overall system reliability of
99.5% (assuming that the system can continue to function as long as at least
one instrument is still working)?
(c) How many instruments in parallel are needed to achieve an overall system reliability of 99.95%?
