Probability of sure event is 1
It is 1.
The probability of an event that is sure not to happen is 0. This means that there is no chance of the event occurring, making it impossible. In probability terms, events are measured on a scale from 0 (impossible) to 1 (certain), so a probability of 0 indicates that the event will never take place.

The probability of the complement of an event, i.e. of the event not happening, is 1 minus the probability of the event.
The complement (not compliment) of the probability of event A is 1 minus the probability of A: that is, it is the probability of A not happening or "not-A" happening.The complement (not compliment) of the probability of event A is 1 minus the probability of A: that is, it is the probability of A not happening or "not-A" happening.The complement (not compliment) of the probability of event A is 1 minus the probability of A: that is, it is the probability of A not happening or "not-A" happening.The complement (not compliment) of the probability of event A is 1 minus the probability of A: that is, it is the probability of A not happening or "not-A" happening.
The probability that an event will not occur is calculated by subtracting the probability of the event occurring from 1. Given that the probability of the event occurring is 0.2, the probability that it will not occur is 1 - 0.2 = 0.8. Thus, there is an 80% chance that the event will not occur.
The probability that an event will occur plus the probability that it will not occur equals 1.
Not sure about the "best" definition. It is the set of all possible outcomes for the event.
A probability event that is impossible is one that will not happen, i.e. its probability is zero.
An event that will definitely happen is an event with 100% probability.
No. The probability of an event ranges from 0 (the event will not happen) to 1 (the event will happen).
