The probability distribution of a random variable whose sample space is the Cartesian product of the sample spaces of its (at least two) component random variables.

plural of probability space

The probability that an event will take place given the restrictive assumption that another event has taken place, or that a combination of other events has taken place. (Mathematically, the definition would be that the conditional probability of B given A is equal to the joint probability of A and B divided by the probability of A.)

(quantum mechanics) A complex number which is the coefficient of a component of a quantum state and whose product with its own complex conjugate gives the probability that the state will collapse to that component (when measured). (Note: the quantum state being thought of as a linear combination of its components.)

plural of balance of probabilities

(law) Alternative form of balance of probabilities

(mathematics) The mathematical study of probability (the likelihood of occurrence of random events in order to predict the behavior of defined systems).

(statistics) A distribution of all possible values of a random variable together with an indication of their probabilities.

(mathematics) A measurable space having a unit measure
