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

if for (-additivity).

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 ;

where (the Poisson distribution);

3) ; is the class of Borel subsets of ;

(the normal distribution);

4) is the space of continuous real functions on 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

where is an arbitrary natural number and (the Wiener measure).
