If 99% of the time it's a false alarm, you just have to take the negation of a current smoke detector state. If it's indicating smoke, everything is fine; if it's not indicating smoke, there is fire. Then you're right 99% of the time.
There was this song about 723934 ultramarine bottles stading on the wall, but I can't remember how it went:
723934 ultramarine bottles stading on the wall,
723934 ultramarine bottles stading on the wall,
and then one ultramarine bottle... ?
