Placing a question mark at the end of a phrase does not make it a sensible question.
Probability
p/(1-p) The sum of the probability of an event occurring plus it not occurring equals 1.
80%
It is the probability of that event.
The probability of an event that is as likely as not to happen is 0.5, or 50%. This means there is an equal chance of the event occurring or not occurring. In probability terms, it indicates that the event has the same likelihood as its complement.
Probability

80%
The likelihood of an event occurring is known as the probability of occurrence. This can be calculated based on previous patterns and other factors.
If the event in question is A and the probability of A occurring is P(A), then the probability of A not occurring is P(A')=1-P(A).
The probability of event A occurring given event B has occurred is an example of conditional probability.
If the probability of an event occurring is p, then 1-p represents the probability of the same event not occurring. The value of p must lie between 0 and 1.
Its proability
It is the probability of that event.
If an event keeps on occurring that means the event is at least annual. If it occurs more than once a year that makes the event perennial or biannual if it only occurs twice.
The probability of an event that is as likely as not to happen is 0.5, or 50%. This means there is an equal chance of the event occurring or not occurring. In probability terms, it indicates that the event has the same likelihood as its complement.
