probability distribution, probability
2020 Mathematics Subject Classification: Primary: 60-01 [MSN][ZBL]
A real non-negative function on a class
of subsets (events) of a non-empty set
(the space of elementary events) forming a
-field (i.e. a set closed with respect to countable set-theoretic operations) such that

Examples of probability measures.
1) ;
is the class of all subsets of
;
(this probability measure corresponds to a random experiment consisting in throwing a symmetrical coin; if heads correspond to 1 while tails correspond to 2, the probability of throwing heads (tails) is 1/2);
2) ;
is the class of all subsets of

4) is the space of continuous real functions

that vanish at the point zero;
is the class of Borel subsets with respect to the topology of uniform convergence;
is the measure which is uniquely defined by the formula
