I'm having trouble, please can somebody help me?

Prove that for all ε>0 there exists a closed set Fc[0,1] such that F http://upload.wikimedia.org/math/e/7...5a73d4e6b8.png http://upload.wikimedia.org/math/2/b...3d4231ab04.png = http://upload.wikimedia.org/math/d/0...709b02e52e.png and λ(F)>1-ε, where λ is the Lebesgue measure.

Thank you very much!
