The Borel-Cantelli Lemmas and the Zero-One Law* This section contains advanced material concerning probabilities of infinite sequence of events. The results rely on limits of sets, introduced in Section A.4.

In intuitive language P(lim sup Ek) is the probability that the events Ek occur "infinitely often" and will be denoted by P(Ek i.o.). The Borel-Cantelli Lemma says that if $(X,\Sigma,\mu)$ is a measure space with $\mu(X)<\infty$ and if $\{E_n\}_{n=1}^\infty$ is a sequence of measurable sets such that $\sum_n\mu(E_n)<\infty$, then $$\mu\left(\bigcap_{n=1}^\infty \bigcup_{k=n}^\infty E_k\right)=\mu\left(\limsup_{n\to\infty} En \right)=0.$$ (For the record, I didn't understand this when I first saw it (or for a long time Since $\{A_n \:\: i.o\}$ is a tail event, combined with Borel-Cantelli lemma, it is clear that the second Borel-Cantelli lemma is equivalent to the converse of the first one.

The Borel-Cantelli lemmas are a set of results that establish if certain events occur inﬁnitely often or only ﬁnitely often. We present here the two most well-known versions of the Borel-Cantelli lemmas. Lemma 10.1(First Borel-Cantellilemma) Let {A n} be a sequence of events such that P∞ n=1 P(A n) <∞.

Proof. Given the identity, Borel-Cantelli Lemmas Suppose that fA n: n 1gis a sequence of events in a probability space. Then the event A(i:o:) = fA n ocurrs for in nitely many n gis given by A(i:o:) = \1 k=1 [1 n=k A n; Lemma 1 Suppose that fA n: n 1gis a sequence of events in a probability space.

Suppose $(X,\Sigma,\mu)$ is a measure space with $\mu(X)< \infty$ and suppose $\{f_n:X\to\mathbb{C}\}$ is a sequence of measurable functions. Het lemma van Borel–Cantelli is een stelling in de kansrekening over een rij gebeurtenissen, genoemd naar de Franse wiskundige Émile Borel en de Italiaanse wiskundige Francesco Cantelli. Een generalisatie van het lemma is van toepassing in de maattheorie.

Starting from some of the basic facts of the axiomatic probability theory, it embodies the classical versions of these lemma, together with the well known as well as the most recent extensions of them due to Barndorff-Nielsen, Balakrishnan and Stepanov, Erdos and I’m looking for an informal and intuitive explanation of the Borel-Cantelli Lemma. The symbolic version can be found here. What is confusing me is what ‘probability of the limit superior equals $0$’ means.
