	Probability - Wikipedia, the free encyclopedia
		In Cox's formulation, probability is taken as a primitive (that is, not further analyzed) and the emphasis is on constructing a consistent assignment of probability values to propositions.
		Probabilities are equivalently expressed as odds, which is the ratio of the probability of one event to the probability of all other events.
		Governments typically apply probability methods in environment regulation where it is called "pathway analysis", and are often measuring well-being using methods that are stochastic in nature, and choosing projects to undertake based on their perceived probable effect on the population as a whole, statistically.

	Probability interpretations - Wikipédia
		There are two broad categories of probability interpretations: Frequentists assign probabilities only to random events according to their relative frequencies of occurrence or to subsets of populations as proportions of the whole.
		Bayesians assign probabilities to any statement, even when no random process is involved, as a way to represent its plausibility.
		The mathematics of probability can be developed on an entirely axiomatic basis that is independent of any interpretation: see the articles on probability theory and probability axioms for a detailed treatment.

		In probability theory and statistics the odds in favor of an event or a proposition are the quantity p / (1 − p), where p is the probability of the event or proposition.
		In probability theory, the cumulative distribution function (abbreviated cdf) completely describes the probability distribution of a real-valued random variable, X. For every real number x, the cdf is given by where the right-hand side represents the probability that the variable X takes on a value less than or...
		In probability and statistics, the t-distribution or Students distribution is a probability distribution that arises in the problem of estimating the mean of a normally distributed population when the sample size is small.

		(There are other rules for quantifying uncertainty, such as the Dempster-Shafer theory and fuzzy logic, but those are essentially different and not compatible with the laws of probability as they are usually understood.) However, there is ongoing debate over what, exactly, the rules apply to; this is the topic of probability interpretations.
		The probability of an event is generally represented as a real number between 0 and 1.
		For example, if two events are assumed equally probable, such as a flipped coin landing heads-up or tails-up, we can express the probability of each event as "1 in 2", or, equivalently, "50%" or "1/2".

	Probability interpretations - Wikipedia, the free encyclopedia
		There are two broad categories of probability interpretations: Frequentists talk about probabilities only when dealing with well defined random experiments.
		The relative frequency of occurrence of an experiment's outcome, when repeating the experiment, is a measure of the probability of that random event.
		Bayesians, on the other hand, assign probabilities to any statement whatsoever, even when no random process is involved, as a way to represent its subjective plausibility.

	Frequency probability - Wikipédia
		Statistical regularity has motivated the development of the relative frequency concept of probability.
		Most of the procedures commonly used to make statistical estimates or tests were developed by statisticians who used this concept exclusively.
		The frequentist position is the one you probably heard at school: perform an experiment lots of times, and measure the proportion where you get a positive result - this proportion, if you perform the experiment enough times, is the probability.

	Comment
		Different interpretations of verbal probability expressions would be unacceptable to the IASC as not only does it have the potential to undermine the credibility of financial reporting, it strikes at the very core of the development of the global accounting language.
		The IASC needs to ensure that the verbal probability expression is interpreted in a consistent manner as different interpretations of the same verbal probability expression have the potential to undermine the credibility of financial reporting.
		While guidance in the interpretation of verbal probability expressions may be useful, the IASC must ensure that it selects terminology that is numerically interpreted as a synonym.

	Probability and Induction
		These theories have various forms: probabilities may be interpreted as actual relative frequencies of occurrent events, or as limiting relative frequencies of infinite sequences of occurrent and imagined events, or as modal relative frequencies of possible events.
		This is probability thought of as a measure of degree of justification or warrant.
		Like subjective probability it is a concept of probability tied to belief systems of a rational agent, but it is not typically developed in terms of variably strong dispositions to act or choose.

	Interpretations of Probability
		The ratio of this number to that of all the cases possible is the measure of this probability, which is thus simply a fraction whose numerator is the number of favorable cases and whose denominator is the number of all the cases possible.
		Probability is thought of as a physical propensity, or disposition, or tendency of a given type of physical situation to yield an outcome of a certain kind, or to yield a long run relative frequency of such an outcome.
		The laws of probability then are claimed to be constraints on these estimates: putative necessary conditions for minimizing her ‘losses’ in a broad sense, be they monetary, or measured by distances from the assignments of these experts.

	ProbabilityTheory - PineWiki
		The usual argument against frequentist probability is that it only works for repeatable experiments, and doesn't allow for statements like "the probability that it will rain tomorrow is 50%" or the even more problematic "based on what I know, there is a 50% probability that it rained yesterday".
		The probability that we roll a 7 is the sum of the cases (1,6), (2,5), (3,4), (4,3), (5,2), and (6,1), or 6/36 = 1/6.
		So one of the ways to compute the probability of two events occurring is to compute the probability of one of them, and the multiply by the probability that the second occurs conditioned on the first.

		One of the simplest of discrete sample spaces is a finite set to each of whose members the same probability 1/n is assigned.
		An example of a sample space that is not discrete is the closed interval [0, 1] to which the length of any subinterval (a, b) is assigned as the probability of that subinterval.
		The probability assigned to any one-member subset is 0.

		On the Propensity Interpretations of Probability in the Analysis of Causation
		It seems that the notion of the propensity interpretations of probability can answer that question: The propensity interpretations of probability consider the conception of "propensity" as "dispositions as causal tendencies," (p.123.) which are represented as probabilities.
		Then, it seems trivial that the propensity interpretations dependent on disposition as causal tendencies explicate causal relevance in terms of probabilistic relations.

		This study extends the study by Laswad and Mak (1997) on the interpretation of probability expressions used in accounting standards by New Zealand standard setters, by comparing the interpretations of standard-setters with practicing accountants.
		The reduction of probability expressions may facilitate greater consistency in the application of accounting standards and consequently greater comparability in financial reporting.
		The results also indicate that, similar to standard-setters, there is considerable disagreement among accountants in the interpretation of probability expressions, which suggest that to enhance comparability in financial reporting, guidance in the interpretation of such phrases is needed.

		This paper is devoted to foundations of probability theory.
		We discuss interpretations of probability, corresponding mathematical formalisms, and applications to quantum physics.
		One of the aims of this paper is to show that the probability model based on Kolmogorov's axiomatics cannot describe all stochastic phenomena, i.e., that quantum physics induces natural restrictions of the use of Kolmogorov's theory and that we need to develop non-Kolmogorov models for describing some quantum phenomena.
