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.

What does equally unlikely mean in probability?
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,
If an event is unlikely to happen its probability is?
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.
What does fair mean from a probability perspective?
From a probability perspective fair means equal probability.
What does and mean in probability?
It means multiply, Probaility of A and B means probability of A multiplied by probability of B.
The mean of a binomial probability distribution can be determined by multiplying?
The mean of a binomial probability distribution can be determined by multiplying the sample size times the probability of success.
