MTBF = 1/failure rate R(t) = e (-t/MTBF) http://www.vicorpower.com/documents/quality/Rel_MTBF.pdf
Reliability is not measured. Reliability is an estimation, typically probablistic.
Everyone defines a failure differently. Who you define as a failure will depend on what you define failure as. What one person sees as a failure, someone else may not see it the same way.
why readabilities only for hardware not software
A bathtub curve is a curve used in reliability engineering, describing a particular form of the hazard function taking into account three categories of failure rate.

What is the failure rate for a franchise? D. 5%
Although both system support high definition output via HDMI and many games are ported to both systems the Xbox 360's failure rate is significantly higher than the Playstation 3 consoles. The Xbox 360 in a recent study had a hardware failure rate of 54.2 % compared to the Playstation 3 consoles 10.6 % failure rate.
since a2+ b2= c2, , and , then the failure rate IS in fact 123,456,789,123,345,634,345%
