Since the unreliability of systems with repairable components cannot be exactly calculated via fault tree, the Expected Number of Failures – which is obtained by integrating the unconditional failure frequency – is considered as it represents a good upper bound.
Expected number of failures.
expected number of crashes.
The building's collapse risk, expected annual losses and the expected number of casualties are calculated.

To address case 1, the breeding organization chose a list of traits for which thresholds were defined and the value of a mating was assessed by the number of faults D, i.e., the number of traits for which the expected EBV of progeny was below these thresholds.
But it camouflaged a number of faults".
