Hi

I need help with the following sets questions

Let A, B and C be sets. Prove that

i)$\displaystyle A\cap(B\setminus C)=(A\cap B)\setminus(A\cap C)$

Give an example of sets A, B and C for which

ii)$\displaystyle A\cup(B\setminus C)\neq(A\cup B)\setminus(A\cup C)$

I have other proofs of various sets but they involved truth tables. But since these sets involve a subtract set(\), i am not sure on what to do.

thanks
