A coin flip
No, it is not.
1/2
Each outcome has a probability of 0.05
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.
It is the probability of an event that will definitely happen.
If the probability of an event is p, then the complementary probability is 1-p.
No, it is not.

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.

Probability of sure event is 1
The probability that an event will occur plus the probability that it will not occur equals 1.
A probability event that is impossible is one that will not happen, i.e. its probability is zero.
