Borel-Cantelli Lemma. Let be a sequence of events occurring with a certain probability distribution, and let be the event consisting of the occurrence of a finite number of events for , 2, . Then the probability of an infinite number of the occurring is zero if. Equivalently, in the extreme case of for all , the probability that none of them occurs is 1 and, in particular, the probability of that a finite number occur is also 1.

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. De Novo Home

It is named after Émile Borel and Francesco Paolo Cantelli, who gave statement to the lemma in the first decades of the 20th century. Eş Borel–Cantelli önermesi olarak da adlandırılan sav, özgün önermenin üst limitinin 1 olması için gerekli ve yeterli koşulları tanımlamaktadır. Sav, bağımsızlık varsayımını tümüyle değiştirerek ( A n ) {\displaystyle (A_{n})} 'nin yeterince büyük n değerleri için sürekli artan bir örüntü oluşturduğunu kabullenmektedir. 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.
