# Math Help - countable events.

1. ## countable events.

if { An} is a sequence of countable events. and A n contains An+1 then limit n-->infinityP(An)=?

if it is 0 , what is the approach?

2. ## Re: countable events.

What is a countable event? I would say that the limit is the probability of the intersection of all the $A_n$.
