Hi I have 2 problems that I need to say whether or not they are true or not and then write a proof for my answer. I am really struggling and could use a little help thank you 1) ...

Given q∈C where C⊂R^n. In addition, given two subsets M1,M2⊂C such that q∈M1, q∈M2 and μ(M1)=μ(M2)=(1/2)μ(C) where μ(S) is the volume of S⊂C. I can easily prove that μ(M1∪M2)<μ(C) with...

thats pretty much it
