## Please help!

I really need help with my homework.

We have E-mesurable set, function f : E -> R is mesurable, f>=0, f is bounded. The rate of the set {x € E : f(x)>=c} is a.

Then the Lebesgue's integral for function f over E is >=a.

I have to prove it. Can anybody give me a hint please?

THANK YOU.
