In general, it is a result in measure theory. It is named after Émile Borel and Francesco Paolo Cantelli, who gave statement to the lemma in the first decades of the 20th century. A related result, sometimes called the second Borel–Cantelli lemma, is a partial converse of the first Borel–Cantelli The celebrated Borel-Cantelli lemma asserts that (A) If ZPiEk) < oo, then P (lim sup Ek) =0; (B) If the events Ek are independent and if Z-^C-^fc)= °° > then P(lim sup Ek) = l. 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.

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. Relation between two versions of the Second Borel Cantelli lemma Hot Network Questions Even if Democrats have control of the senate, won't new legislation just be blocked with a filibuster? Borel-Cantelli Lemmas . Once we have understood limit inferior/superior of sequence of sets and the continuity property of probability measure, proving the Borel-Cantelli Lemmas is straightforward. So, here are the lemmas and their proof.
