Let S be partitioned into r×s disjoint sets E_i and F_j where the general subset is denoted E_i intersection F_j. Then the marginal probability of E_i is ...

If one event can occur in m ways and a second can occur independently of the first in n ways, then the two events can occur in mn ways.

n events are said to be mutually exclusive if the occurrence of any one of them precludes any of the others. Therefore, for events X_1, ..., X_n, the conditional probability ...

The probability that a variate would assume a value greater than or equal to the observed value strictly by chance: P(z>=z_(observed)).

The portion of the probability distribution which has a P-value equal to the observed P-value.

If B superset A (B is a superset of A), then P(A)<=P(B).

Define T as the set of all points t with probabilities P(x) such that a>t=>P(a<=x<=a+da)<P_0 or a<t=>P(a<=x<=a+da)<P_0, where P_0 is a point probability (often, the ...

A lottery in which three numbers are picked at random from the integers 1-14.

A term in social choice theory meaning invariance of a result under permutation of voters.

A property of a space which is also true of each of its subspaces. Being "first-countable" is hereditary, but having a given genus is not.
