The probability that an event will occur plus the probability that it will not occur equals 1.
If the event in question is A and the probability of A occurring is P(A), then the probability of A not occurring is P(A')=1-P(A).
These events are complementary. Let P(A) = probability event will occur. Then the probability it will not occur is: 1 - P(A).
If the probability of an event occurring is p, then 1-p represents the probability of the same event not occurring. The value of p must lie between 0 and 1.
The complement of an event occurring is that it does not occur.
p/(1-p) the relation between both outcomes.
Let p = probability the event will occur; and q = probability the event will not occur. The relationship is p=1-q or q=1-p.
Probability can not be less than 0 or greater than 1. A probability of 0 means there is no possibility whatsoever of an event occurring. A probability of 1 means that the event is guaranteed to occur no matter what.
an impossible event has a probability of 0, it will never occur a certain event has a probability of 1, it will always occur
compliment- it's a word for the probability minus one, so it something has a .6 probability, the probability(compliment) it woun't occur is .4 The answer for the Statistic Crossword Puzzle is "odds"
odds"The odds against an event is a ratio of the probability that the event will fail to occur (failure) to the probability that the event will occur (success). To find odds you must first know or determine the probability of success and the probability of failure.Odds against event = P(event fails to occur)/P(event occurs) = P(failure)/P(success)The odds in favor of an event are expressed as a ratio of the probability that the event will occur to the probability that the event will fail to occur.Odds in favor of event = P(event occurs)/P(event fails to occur) = P(success)/P(failure)"Allen R.

the probability a certain event will occur :-)
If the event is truly impossible, it has a zero probability of occurring. The definition of impossible is "not able to occur, exist, or be done," so that means there's no chance of it happening.
The word probability is a noun. Probability is an event that is likely to occur.
No; if it is certain not to occur the probability is 0.
Probability is a measure of the expectation that an event will occur or a statement is true. Probabilities are given a value between 0 (will not occur) and 1 (will occur). The higher the probability of an event, the more certain we are that the event will occur.
Its probability. The probability for a certainty is 1.
How likely it is for an event to occur.
If the event will definitely occur, then its probability is 1.Not asked, but answered for completeness sake - if the event will definitely not occur, then its probability is 0. All probabilities lie between 0 and 1, inclusive.
Probability is the measure of how likely an event is. ... The probability of event A is the number of ways event A can occur divided by the total number of possible.
