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 you are using it in terms of an event (aka rolling a dice, flipping a coin, etc.) it means there is a 50% chance of it happening and not happening. It can be equal to 50% or 1/2 or anything equal to those!
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.
Theoretical probability is the probability of an event when all outcomes are equally likely. With theoretical probability, you determine the probability by dividing the number of ways the event can occur by the total number of equally likely outcomes.
Theoretical probability
Two events that have the same chance of happening. For example, if I flip a coin the event of obtaining a 'head' is equally as likely as the event of obtaining a 'tail'. But equally likely does not mean 0.5 probability. It's possible that it's equally likely that someone in Ontario, Canada will die from being stung by a wasp as from being electrocuted in their kitchen at home. Neither event is very likely but the two events could be equally likely.
The two events have the same probability of happening.

A set of outcomes are said to be equally like if the probability for the occurrence of any of the is the same as that for any other. The phase, "at random" is used to indicate that the probability for each individual outcome is the same.

probability is 1/6, or unlikely
Theoretical probability
Theoretical probability- what the probability "should be" if all outcomes are equally likely.
It is a probability of between 0.3 and 0.7
It can be termed unlikely.
The modelling of a probability distribution function for an event from a theoretical approach.
