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...

for example if A = {a,b,c} then all possible subsets are {a}, {b}, {c}, {a,b}, {a,c}, {b,c},{a,b,c} and combinations of subsets which cover the original set are: {{a},{b,c}} and {{a},{b},{c}} and...

set theory

Professor says this question is a lot simpler than I think

This is a set theory problem my teacher say its easier than I think but I don't understand.

Let A, B and C be different sets containing letters of the alphabet. Explain why there must exist some letter that is either contained in exactly one of the sets or contained in exactly two...

Show that if f is a function of one variable that is recursive, nondecreasing, and unbounded then its range is an infinite recursive set. and Show that every infinite recursive set is the...

Suppose that R=R1⊕R2⊕…….⊕Rn where each Ri is a principal ideal ring. Verify that R is also a principal ideal ring. please I want help with that

Let U={w, x, y,1, 2, 3} , A ={2, y} , B = {x, y, 3}, C ={w, y,1} Find AU B' Find n(B-A) find AXB

I can't find an example of how to solve when n(A) and n(B) are not given. Please help.
