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.
Biennial (biannual is twice a yesr)
An event occurring every two years is referred to as a biennial event. This pattern indicates that the event happens once every two years.
The word "biennial" means an event that either lasts for two years, or it happens every two years.
according to me it is biennial.
An event that is not planned to happen is called an "unplanned event" or "unexpected event." These events can also be referred to as "incidents," "accidents," or "contingencies," depending on the context. They often require quick responses and adaptations, as they can disrupt normal procedures or expectations.
