The celebrated Borel–Cantelli Lemma is important and useful for proving the laws of large numbers in the strong form. Consider a sequence of random events {A n } on a probability space (Ω, { F}, P), and we are interested in the question of whether infinitely many random events occur or if possibly only a finite number of them occur.
The upper limit of the sequence {A n } is the random event defined by
which occurs if and only if an infinite number of events A n occur. This i.o. stands for “infinitely often.”
Below we shall use the fact that if {A n } is a sequence of random events, then
The Borel–Cantelli Lemma
Lemma 1
If ∑ ∞ n = 1 P(A n ) < ∞, then P(lim sup n → ∞ A n ) = 0. If the random events A 1, A...
