Suppose there is an event A and the probability of A happening is Pr(A). Then the complementary event is that A does not happen or that "not-A" happens: this is often denoted by A'.Then Pr(A') = 1 - Pr(A).Suppose there is an event A and the probability of A happening is Pr(A).

An event that occurs every 18 months is often referred to as a "biennial" event, although "biennial" typically means every two years. In a more specific context, it may be described as an "18-month cycle" or "semiannual" depending on the nature of the event. In scientific or astronomical contexts, specific terms might be used to denote cycles of that length, but there isn't a widely recognized single term for an 18-month event.
