guys im bit confused with the statement borel cantelli lemma 2 :(adsbygoogle = window.adsbygoogle || []).push({});

"If the events En are independent and the sum of the probabilities of the En diverges to infinity, then the probability that infinitely many of them occur is 1"

this state if probability of A occur > 0 .

and if the probabilities of A diverges to infinity, then the probability that infinitely many of A occur is 1

the problem is

if probability of opposite A, event[not A] > 0

and if the probabilities of "not A" diverges to infinity

then the probability that infinetely many of [not A] occur is 1.

in other way the probability of A doest occur is 1 too?

this correct?

or i made a mistake ? thank you
