## probability

(ˌprɒbəˈbɪlɪtɪ)
n, pl -ties
1. the condition of being probable
2. an event or other thing that is probable
3. (Statistics) statistics a measure or estimate of the degree of confidence one may have in the occurrence of an event, measured on a scale from zero (impossibility) to one (certainty). It may be defined as the proportion of favourable outcomes to the total number of possibilities if these are indifferent (mathematical probability), or the proportion observed in a sample (empirical probability), or the limit of this as the sample size tends to infinity (relative frequency), or by more subjective criteria (subjective probability)

## prob•a•bil•i•ty

(ˌprɒb əˈbɪl ɪ ti)

1. the quality or fact of being probable.
2. a probable event, circumstance, etc.
3. Statistics.
a. the relative possibility that an event will occur, as expressed by the ratio of the number of actual occurrences to the total number of possible occurrences.
b. the relative frequency with which an event occurs or is likely to occur.

## prob·a·bil·i·ty

(prŏb′ə-bĭl′ĭ-tē)
A number expressing the likelihood of the occurrence of a given event, especially a fraction expressing how many times the event will happen in a given number of tests or experiments. For example, when rolling a six-sided die, the probability of rolling a particular side is 1 in 6, or 1/6 .

Relying instead on the mathematical supplement of the probability calculus would be so awkward and incomplete as to be nonsensible.
If anything can occur without a reason or cause of some sort, which is precisely what indeterminism means, then it is completely arbitrary to eliminate any of those possible outcomes from your probability calculus. This is just as true of the a priori methods as it is for the classical method.

Through these linked realities, Coen reveals seven underlying liberal ideological dichotomies and applies her argument for the probability calculus in each case: public and private; particular and universal; inclusion and exclusion; subjectivity and objectivity; rationality and instinct or uncertainty; nature and nurture; and individual and collective.
Needless to say, the decision to prepare will be based almost entirely upon a probability calculus. Among other important factors, cost-benefit analysis should take public relations into account: No company would ever want to be charged with irresponsible reactions to a lethal disease.
