 additive law of probability   قانون ِ بردایشی ِ شوانایی   qânun-e bardâyeši-ye šavânâyiFr.: loi additive de probabilité   If E1, E2, ..., En are n → mutually exclusive events, then the probability of occurrence of at least one of them is the sum of their individual probabilities: P(E1 + E2 + ... + En) = P(E1) + P(E2) + ... + P(En).→ additive; → law; → probability. conditional probability   شوانایی ِ بوتاری   šavânâyi-ye butâriFr.: probabilité conditionnelle   Of an event B in relationship to an event A, the probability that event B occurs given that event A has already occurred. The notation for conditional probability is P(B|A), read as the probability of B given A: P(B|A) = P(A ∩ B)/P(A). → Bayes' theorem. conservation of probability   پتایش ِ شوانایی، پایندگی ِ ~   -patâyeše šavânâyi, pâyandegi-ye ~Fr.: conservation de probabilité   A principle according to which the sum of probabilities of all possible states that might come out of an initial state equals the probability of the initial state.→ conservation; → probability. objective probability   شوانایی ِ بر‌آختی   šavânâi-ye barâxtiFr.: probabilité objective   A probability determined by the long-term frequency of an event; in contrast to subjective probability.→ objective; → probability. probability   شوانایی   šavânâyiFr.: probabilité   1) General: The quality or fact of being probable. A strong → likelihood or chance of something. 2) Statistics: The branch of → mathematics that studies the possible outcomes of given events and their relative distributions. → probability theory.From → probable + → -ity. probability curve   خم ِ شوانایی   xam-e šavânâyiFr.: courbe de probabilité   A curve that describes the distribution of probability over the values of a random variable.→ probability; → curve. probability density function   کریای ِ چگالی ِ شوانایی   karyâ-ye cagâli-ye šavânâyiFr.: fonction de densité de probabilité   A mathematical function whose integral over any interval gives the probability that a continuous → random variable has values in this interval. Also known as → density function, frequency function, → probability function.→ probability; → density; → function. probability distribution   واباژش ِ شوانایی   vâbâžeš-e šavânâyiFr.: distribution de probabilité   The function that describes the range of possible values that a random variable can attain and the probability that the value of the random variable is within any (measurable) subset of that range.→ probability; → distribution. probability function   کریای ِ شوانایی   karyâ-ye šavânâyiFr.: fonction de probabilité   A function that represents a probability distribution in terms of integrals. Also called probability density function or density function.→ probability; → function. probability theory   نگره‌ی ِ شوانایی   negare-ye šavânâyiFr.: théorie des probabilités   A branch of → mathematics with its own axioms and methods, which is based on the concept of → randomness and is concerned with the possible outcome of given → events and their relative → likelihoods and → distributions.→ probability; → theory. transition probability   شوانایی ِ گذرشی   šavânâyi-ye gozarešiFr.: probabilité de transition   The probability that a quantum-mechanical system will make a transition from a given initial state to a given final state.→ transition; → probability.
