Need help with this - just had this on a test and this is driving me crazy - PLEASE HELP!!(adsbygoogle = window.adsbygoogle || []).push({});

Let {[itex]f_{n}[/itex]} be a sequence of MEASURABLE real valued functions. Prove that there exists a sequence of positive real numbers {[itex]c_{n}[/itex]} such that [itex]\sum c_{n}f_{n}[/itex] converges for almost every x [itex]\in[/itex] [itex]\Re[/itex]

How is it possible for this to be true??? Please help!!
