A likely event, mathematically, is more then 50% likely to happen. An unlikely event is less then 50% likely to happen.
One doesn't have *un* at the start.
If the even is never going to take place, and it is for sure, then it's probability will be 0. For example, if the event is : A child being born with powers like Superman. For this event, the probability would be 0! But in practicality, if the event is unlikely to happen, it's probability is likely to be nearer to 0. Keeping in mind the difference between "unlikely to happen" and "never going to happen for sure". Because there is a possibility that the event that is unlikely to happen may just happen once in a thousand years. So in this case, the probability will be very very close to 0, but it will not be 0 exactly.
Two events are equally unlikely if the probability that they do not happen is the same for each event. And, since the probability of an event happening and not happening must add to 1, equally unlikely events are also equally likely,
In common usage, unlikely means a low probability of occurrence. But as a term in mathematics, an unlikely event is not rigorously defined as a "low number" is subjective. Certainly, in a comparative sense, i.e. event A is less likely to occur than event B, we can state that the probability of occurrence of A is less than B.

It is a probability of between 0.3 and 0.7
If the even is never going to take place, and it is for sure, then it's probability will be 0. For example, if the event is : A child being born with powers like Superman. For this event, the probability would be 0! But in practicality, if the event is unlikely to happen, it's probability is likely to be nearer to 0.

So in this case, the probability will be very very close to 0, but it will not be 0 exactly.
An improbable occurrence refers to an event that is unlikely or highly unlikely to happen based on existing circumstances or statistical probabilities. It suggests that the event is unexpected or rare due to factors that make it unlikely to occur.
It is a real number between 0.5 and 1. Whether or not it is independent makes no difference to this answer.
Two events are equally unlikely if the probability that they do not happen is the same for each event. And, since the probability of an event happening and not happening must add to 1, equally unlikely events are also equally likely,
Level of probability of an adverse event occurring
In common usage, unlikely means a low probability of occurrence. But as a term in mathematics, an unlikely event is not rigorously defined as a "low number" is subjective. Certainly, in a comparative sense, i.e. event A is less likely to occur than event B, we can state that the probability of occurrence of A is less than B.

The probability of an adverse or critical event occurring is what words like frequency, likely, occasional, seldom, and unlikely refer to in the risk assessment matrix.
