(mathematics) A mathematical measure on a probability space that can take on values between 0 and 1, with 0 corresponding to the empty set and 1 to the entire space.

plural of probability space

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.

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.)
