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 complement of an event occurring is that it does not occur.
n event A is said to be less probable than an event B if the probability of A occurring is smaller than that of B occurring.
The probability of an event occurring within 5 standard deviations from the mean is extremely rare, as it falls outside the normal range of outcomes.
It means that there is a 61.8% chance of the event occurring.
It is the likelihood of any particular event occurring.
p/(1-p) The sum of the probability of an event occurring plus it not occurring equals 1.
'Chance' is NOT used in mathemetical statistics. The correct word is 'Probability'. Algebraically expressed as P( something occurring) = ( any decimal value between '0' and '1'. P( ...) = 0 ( Will NOT happen) P( ..._ = 1 ( Will definitely happen). e.g. P( night follows day) = 1 ( It will definitely happen). P( heads on coin toss) = 0.5 ( Because it may com down on the reverse side(tails)). NB If you have a probability answer 'outside' '0' & '1', then the answer in incorrect.!!! Start again!!!!!

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.
