Let a parallel system be composed of n$=2$ identical components each with

FR $(\backslash$lambda $)$ of $0\mathrm{.}011$ and mission time T$=10$ hours, only one of which is

needed for system success. Calculate:

$$ Total system reliability

$$ Mean Time to Failure $($in hours$)$

$$ The failure $($hazard$)$ rate for the system

$($c$)$ A computer system is composed of $5$ identical terminals in series. Let the

required system reliability for unit mission time $($T$=1)$ be R $(1)=0\mathrm{.}998.$

Calculate:

$$ Component reliability and failure rate

$$ Total system reliability and failure rate for mission time T$=10$

hours

$$ What is the mission time T that accomplishes a missio
