Reliability is most often quantified as the probability that the device or system has not failed (is alive) at a particular time: R(t) = Pr{lifetime > t} = 1 − F(t), where F is the cumulative distribution function of the life-times. This function is often also called the survived function. Failure-rate function; Reliability function ; System reliability.
