# A frequently used statement on infinite sequences of random events. Let $A_1,\dots, A_n, \dots$ be a sequence of events from a certain probability space and let $A$ be the event consisting in the occurrence of (only) a finite number out of the events $A_n$, $n=1,2\dots$. Then, according to the Borel–Cantelli lemma, if

Borel-Cantelli lemmas and the law of large numbers Gunnar Englund & Timo Koski Matematisk statistik KTH 2008 1 Introduction Borel-Cantelli lemmas are interesting and useful results especially for proving the law of large numbers in the strong form.

Introduction If (A,),~ is a sequence of independent events, then the relation (1) IP(A,)=co => P UAm = 1 n=l n=1 m=n holds. This is the assertion of the second Borel-Cantelli lemma.

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. Een aanverwant resultaat, dat een gedeeltelijke omkering is van het lemma, wordt wel Prokhorov, A.V.

So, here are the lemmas and their proof.

En la teoría de las probabilidades, medida e integración, el lema de Borel-Cantelli asegura la finitud en casi todos los puntos de la suma de funciones integrables positivas si es que la suma de sus integrales es finita. I have just modified one external link on Borel–Cantelli lemma.

### Il Lemma di Borel-Cantelli è un risultato di teoria della probabilità e teoria della misura fondamentale per la dimostrazione della legge forte dei grandi numeri. Siano ( Ω , E , μ ) {\displaystyle (\Omega ,{\mathcal {E}},\mu )} uno spazio di misura e { S n } n ∈ N {\displaystyle \{S_{n}\}_{n\in \mathbb {N} }} una successione di sottoinsiemi misurabili di Ω {\displaystyle \Omega } .

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.

Despite it being usually called just a lemma, it is without any doubts one of the most important and foundational results of probability theory: it is one of the essential zero-one laws, and it allows us to prove a variety of almost-sure results.

In probability theory, the Borel–Cantelli lemma is a theorem about sequences of events. In general, it is a result in measure theory.
