What is the probability if something can never occur?

Zero.


The probability that an event will occur is 0.2. what is the probability that the event will not occur?

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.


How are ratio and probability the same?

A ratio is a comparison of the relative size of two different things. Probability is the change that something will (or will not) occur. Probability can be expressed as a ratio of Yes to No (or, "will occur" to "won't occur"). That is, Probability is the relative size of Yes to No. So, if something is said to have a 60% Probability of occurring, what that is indicating is that, out of 100 tries, 60 will be the outcome indicated. While probability is usually expressed as a percentage, it is entirely possible to express it as a ratio. In the aforementioned example, a 60% Probability of occurrence could also be said to be a 60:40 (or, reduced, 3:2) ratio in favor of happening.


What is probability mean?

probably means that something or which is not sure . LIKE :- I PROBABLY GET THIS ANSWER RIGHT.


What does the probability of one mean?

A probability of one means that the outcome will definitely occur.Not asked, but answered for completeness sake - a probability of zero means that the outcome will definitely not occur. Probability always lies between zero and one, inclusive.

Probability is the what that something will or will not occur?

Probability is the likelihood that something will occur. If you subtract it from 1, we get the likelihood (or probability) that it will not occur. If a coin is tossed and rolls heads 6 times, the (empirical) probability of obtaining a head is 6/10 or .6. 1-.6 =.4 is the empirical probability (or likelihood) of not getting a head.

What is a probabilty?

Probability is the likelihood of something happening. It is the extent to which something is likely or unlikely to occur.


What best describes probablity?

Probability is a numeric expression of the "odds" that something will happen.


What is the probability of an event occurring to the probability that it will not occur?

The probability that an event will occur plus the probability that it will not occur equals 1.


Define the probability of something happening?

The probability that something will happen is the number of times that that something can occur divided by the number of times that anything can occur. An example would be to consider a standard deck of 52 cards. There are 4 sevens in the deck, so the probability of drawing a seven is 4 in 52, or 1 in 13, or about 0.0769.


Probability of an event occurring to the probability that it won't occur?

These events are complementary. Let P(A) = probability event will occur. Then the probability it will not occur is: 1 - P(A).
