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,

What is the definition of or in a probability?

My answer for probability Probability is the chance that something will happen - how likely it is that some event will happen.

Example: "It is unlikely to rain tomorrow".

What is the difference between likely and unlikely?

Likely refers to a high probability or a strong chance of something happening, while unlikely refers to a low probability or a slim chance of something happening. In other words, likely means it is probable or expected to occur, whereas unlikely means it is improbable or not expected to occur.


What is the meaning when the probability of the event equals 0?

It's unlikely to happen


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.


Is 1 in 10 highly unlikely?

It is unlikely. Most statisticians would not consider the occurrence of an event with that probability as sufficient evidence to reject a hypothesis.
