proabability of an absolutely certain event is 1.
e.g. Night follows day is absolutely certain .
Hence
P(certain) = 1

What is the best definition of sample space of a probability event?
Not sure about the "best" definition. It is the set of all possible outcomes for the event.
What is probability?
probably means that something or which is not sure . LIKE :- I PROBABLY GET THIS ANSWER RIGHT.
What is the probability of a sure event?
It is 1.
What is the probability of a given number to be prime?
I don't think that there is one, as there are prime numbers for infinity, and they are not at an equal distance or at a distance which goes up at a certain rate, and so I'm pretty sure that there isn't one! I hope this answers your question!I don't think that there is one, as there are prime numbers for infinity, and they are not at an equal distance or at a distance which goes up at a certain rate, and so I'm pretty sure that there isn't one!

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.
