Proof for all sets A, B, and C:
A complement Union B complement = (A Intercept B) complement.
can someone help??
Note: to show that two set are equal we need to show
and
let by definition
by negation
by definition
(def of compliment) Since x is not in A and B it must be in
This is half the proof Now you need to show the 2nd part.
Good luck
P.s. I think this is one form of DeMorgans Law.
