Alert fatigue is arithmetic

Alert fatigue is a designed-in property of any large expectation suite.

E [false alarms] = assertions \times α, P (\geq 1) = 1 - (1 - α)^{n}

Worked examples, recomputed

Every number the mechanisms quote for this relationship is recomputed from it, so none of them disagrees with it.

Each mechanism states it in its own names. The general symbol each name stands for is shown with it.
