    an exercise about lebesgue measure

    let $\{E_{n}\}_{n\in\Bbb N}$ be a sequence of measurable subsets such that $E_n \subseteq (0,1)$ and let $\limsup_{n\to\infty}  m(E_{n})=1$, prove that $m(\bigcap_{k=1}^\infty E_{k}) > 0$, where m is the measure of Lebesgue.


    Any ideas on how to do this?

    Re: an exercise about lebesgue measure

    P.S. there was an errata corrige on the book, the exercise asks to prove that exists a subsequence E_{n_{k}} such that m(\bigcap_{k=1}^{\infty}E_{n_{k}})>0

    Sorry for the double post. I found it only now.
