Semi is Latin for "every other". Annual means "year". That means "every other year" in this case.
Bi-annual is a word that refers to an event that happens twice a year. The word 'semiannual' is often substituted for biannual as well, and means the same thing.

Well, honey, you use "semiannual" in a sentence by saying something like, "I have a dental check-up scheduled for my semiannual cleaning next week." It means something that occurs twice a year, so don't go confusing it with biannual, which means something that happens every two years. Just remember, semiannual means twice a year, and you'll be golden.
The frequency refers to how often an event occurs over a specific period of time, while the duration is the length of time that event lasts.
The likelihood that an event will occur refers to the probability or chance of that event happening. It is often expressed as a fraction, decimal, or percentage, indicating how likely the event is compared to all possible outcomes. For example, a likelihood of 0.5 means there is a 50% chance the event will occur. Understanding likelihood helps in decision-making and risk assessment across various fields.
The probability that an event will not occur is calculated by subtracting the probability of the event occurring from 1. Given that the probability of the event occurring is 0.2, the probability that it will not occur is 1 - 0.2 = 0.8. Thus, there is an 80% chance that the event will not occur.
