Web0-1 LAWS FOR REGULAR CONDITIONAL DISTRIBUTIONS PATRIZIA BERTI AND PIETRO RIGO Abstract. Let (Ω,B,P) be a probability space, A ⊂ B a sub-σ-field, and µ a regular conditional distribution for P given A. Necessary and sufficient conditions for µ(ω)(A) to be 0-1, for all A ∈ A and ω ∈ A0, where A0 ∈ A and P(A0) = 1, are given. Such ... Webthen that pairwise independence is sufficient for the second Borel-Cantelli lemma! 2.3. Kolmogorov’s zero-one law. If (;F;P) is a probability space, the set of all events that have probability equal to 0 or to 1 form a sigma algebra. Zero-one laws are theorems that (in special situations) identify specific sub-sigma-algebras of this.

WebFeb 15, 2024 · While the zero–one laws are not required in the following proof, they do imply that the indicated limit of the averages is either sure to exist or sure not to exist. A good warm-up exercise is to work out a proof using the Borel–Cantelli lemma I based on Chebyshev inequality estimates, assuming finite fourth moments (Exercise 1).
The lemma states that, under certain conditions, an event will have probability of either zero or one. Accordingly, it is the best-known of a class of similar theorems, known as zero-one laws. Other examples include Kolmogorov's zero–one law and the Hewitt–Savage zero–one law. See more In probability theory, the Borel–Cantelli lemma is a theorem about sequences of events.
