A probability assignment is a numerical encoding of the relative state of knowledge.

Mathematical statement about how likely it is that something will happen.

The long term frequency of an event relative to all alternative events, and usually expressed as decimal fraction.

Probability means: 1. being probable, 2. something that is probable, 3. a ratio expressing the chances that a certain event will occur, and 4. a branch of mathematics studying chances of random events. To find the probability of rolling a 3 on a six-sided die, you roll the die 1,000,000 times. You roll a 3 166,549 times. You find the proportion of 3's by dividing: 166,549 / 1,000,000 = 0.166549. The probability of rolling a 3 on this particular die is about 1/6.

The odds of an event occuring. 50% means the event will occur 1 out of every 2 times.

The mathematical probability of an outcome. Expressed as a percent.

A number from 0 to 1 that indicates the likelihood that something (an event) will happen. The closer a probability is to 1, the more likely it is that an event will happen. An event with a probability of 0 is impossible. An event with a probability of 1 is a certainty.

distribution: The possible outcomes of an experiment along with their associated probabilities. Specific probability distributions, such as the normal, t, and F have been derived from sets of assumptions about how scores are generated and the way they are combined. When the assumptions are correct, the probability distribution may be used to determine the critical value for a significance test. In practice, the distribution is presumed applicable given the structure of the experiment and the assumptions are not specifically checked.

The chance that a prescribed event will occur, represented as a pure number p in the range 0 Â£[â‰¤] p Â£[â‰¤] 1. The probability of an impossible event is zero and that of an inevitable event is unity. Probability is estimated empirically by relative frequency, that is, the number of times the particular event occurs divided by the total count of all events in the class considered. See probability theory.

The subjective assignment of likelihood of future events; or the frequency of occurrence of an experimental or observations outcome. It refers to the uncertainty or partial knowledge associated with decision making.

The possibility that an event will occur, as expressed by the ratio of the number of actual occurances to the total of possible occurances.

The chance that an event occurs. It is usually expressed as a percent. Zero percent denotes impossibility, while 100% denotes certainty

Chance, expressed as a percentage or decimal. E.g. a 50-50 chance is a probability of 50%, or 0.50. Odds of 3 to 1 correspond to a probability of 25%.

A measure of the chance of an event, which takes a value between 0 and 1. It can be estimated from data, calculated mathematically from theoretical considerations or from a combination of both.

The chances or odds of something occurring. For example, the probability of a coin turning up heads is 50%.

The likelihood that an event will occur, on a scale ranging from 0 (no chance at all) to 1 (or 100% - totally predictable). Related to odds.

A statistical measure of the likely frequency or occurrence of flooding.

The ratio of the number of specific events to the number of all possible events (i.e., p = # specific / # specific + # other). Probabilities can range from zero (i.e., impossible) to one (i.e., every time). The probability of an event differs from the odds of an event in that the denominator for calculating odds is the non-events and the denominator for probability is the total of all events.

A number representing the chance that a given event will occur. The range is from 0% for an impossible event, to 100% for an inevitable event.

The number of successful outcomes divided by the number of possible outcomes in an experiment.

A measure of how likely something is. For example, probability could be written as “p.05,” which means that based on chance alone this thing should happen fewer than 5 times in 100.

A measure associated with an event, A, and denoted P(A) that takes a value such that

When an event can occur in a finite number of discrete outcomes, the probability of an event is the ratio of the number of ways in which the event can occur to the total number of possibilities, assuming that each of them is equally likely. Definitions: Q

likelihood of a risk occurring.

A number from 0 to 1 that tells how likely it is that a given event will occur. The closer to 1, the more likely the event is to occur. The closer to 0, the less likely it is to occur.

Probability is a branch of mathematics having to do with the possible outcomes of given events and their relative likelihoods and distributions. The word "probability" is used to mean the chance that a particular event or set of events will occur. It usually is expressed on a linear scale from 0 (impossibility) to 1 (certainty) or as a percentage between 0 and 100%. The analysis of events governed by probability is called Statistics.

a measure of the likelihood that a given event will occur; expressed as a number between 0 and 1 (see Empirical probability and Theoretical/expected probabilit

Probability is the 'chance' or 'risk' of something happening. (It is the word from which springs the 'p' in the notion 'p value'.)

A number between 0 and 1 which represents how likely an event is to occur. Events with probability equal to 0 never occur. Events with probability equal to 1 always occur. In data analysis, probability is normally defined in terms of the relative frequency of occurrence of an event which can be repeated many times. For example, if you repeatedly sample temperatures from a process and get values below 150 degrees half the time, then the "probability" of getting a reading below 150 degrees is equal to 0.5 or 50%. In daily life, we sometimes use probability in a different sense, i.e., to express our degree of belief about the likelihood of an event which can not be repeated indefinitely under identical conditions. For example, you might say that the chance of getting a raise this year is "one in a million". Such "subjective" probabilities are used in statistical decision theory.

A number between one and zero which denotes how likely an event is to happen. Multiplied by 100, it becomes a percentage.

The likelihood that results in a test were due to chance.

The likelihood of an event happening.

A probability provides a quantitative description of the likely occurrence of a particular event. Probability is conventionally expressed on a scale from 0 to 1; a rare event has a probability close to 0, a very common event has a probability close to 1. (From the Department of Statistics of the University of Glasgow, http://www.stats.gla.ac.uk/)

In the MOF risk model, the likelihood that the condition will occur. (Note that this is not the likelihood of the consequence. It is assumed that if the condition happens, the consequence is a guaranteed result.) Probability is measured on a numeric scale, and it is never zero (because a risk that can't happen isn't something to manage) and never 100 percent (because that condition would be guaranteed: a known problem, not a risk).

A numerical likelihood that a particular outcome will occur.

The expectation of the occurrence of a particular event; the likelihood that a random event will occur.

The likelihood of a specific event or outcome, measured by the ratio of specific events or outcomes to the total number of possible events or outcomes.

(noun) Something that is likely to happen or exist.

The likelihood of something happening or being true.

The chance of occurrence or recurrence of a specified event within a unit of time, commonly expressed in 3 ways. Thus a 10-year flood has a chance of 0.1 per year and is also called a 10%-chance flood.

The likelihood of something. For example, if the probability that it is going to rain this evening is 50%, then the likelihood that it will rain this evening is 50-50. The probability of an event can be calculated in specific ways; an inferential test is one that calculates the probability that the null hypothesis is 'true'. Usually probability makes an 'all else being equal' assumption, i.e. that things that might influence the outcome of an event that we cannot measure or account for (or even know exists) has, in fact, no influence at all

is a number between 0 (never occur) and 1 (always occur) which represents how likely an event is to occur. Probability is normally defined in terms of the relative frequency of occurrence of an event which can be repeated many times. [6

The likelihood of an occurrence.

A statistical measure of the likelihood that a hazard event will occur.

The number of times an outcome occurs in the total number of trials. If A is the outcome, the probability of A is denoted P (A).

The chance of something happening. Calculated from the number of occurrences divided by number of times that occurrence could have occurred.

The measure of how likely it is for an event to occur. The probability of an event is always a number between zero and 100%. The meaning (interpretation) of probability is the subject of theories of probability. However, any rule for assigning probabilities to events has to satisfy the axioms of probability.

A number from 0 to 1 that indicates how likely something is to happen.

The chance, or likelihood, that a certain event will occur.

The probability of an event represents the chance of its occurrence. The judgment can be expressed in the form of a probability distribution.

A mathematical calculation that establishes the likelihood of any event occurring.

The likelihood or relative frequency of an event expressed in a number between zero and one. The throw of a die is an example. The probability of throwing five is found by dividing the number of faces that have a five (1) by the total number of faces (6). That is a probability of one-sixth or one divided by six, which is .17. See also Degree of Risk, Law of Large Numbers, and Odds.
