A radio is composed of two primary components, a power
supply (component A) and a transceiver (component B), that operate in series.
The two components have the following reliability functions:

Find the MTTF and the reliability at 103 operating hours for
each of the following configurations:

(a) Two radios operating in parallel (high-level active
redundancy with 2 “A-B’s”).

(b) One radio configured in low-level active redundancy with
2 “A’s” and 2 “B’s” where additional switching logic is
necessary and the switching mechanism has the reliability function
