(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

(mathematics) The probability that a certain outcome will occur, as determined through experiment.

(mathematics) the probability that a certain outcome will occur, as determined through reasoning or calculation.

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.)
