Prove for all sets A,B, and C : A complement UNION B complement = (A intercept B) complement help me out here please

Proof for all sets A, B, and C: A complement U B complement = (A Intercept B) complement. can someone help??

Proof subset? Given three sets A, B, and C, set X = (A-B) U (B-C) U (C-A) and Y = (A∩B∩C) complement C. Prove that X is subset of Y. Is Y necessarily a subset of X? If yes, prove it. If no, why? ---When I draw the two venn diagrams X and Y, they are the same, but I don't know how to prove...

Goodevening, I am confused with Venn diagrams questions(2/3 circle diagrams). Can i find some online resources which explains its concepts(including advanced concepts). Eg. 3circled(A,B,C) diagram is there. Find minimum/max. possible of ONLY A such that B is minimum/maximum - how to do these...

Given S is set for all real number. A is set for all even number, B is set for all positive integer, C is set for odd number represent the relationship between the sets with Venn diagram. This question is seems easy. However, there is a problem that how can we illustrate the three sets in...

just a clarification cause it's been so long if you have intersection in a venn diagram, is it general practice to label the section including the intersecting diagrams. say you have two sets of 10 with 5 things in the intersect. do you label it 10 in the 2 sets and 5 in the intersect. or. 5...

I am trying to prove this as false. Let A, B, C be any three sets. If A U C = B U C then B = C. I can draw a Venn Diagram to prove this and I can assign values to the sets to prove it, but how can I prove without doing this? Also is the counter value A U C = B U C then B not equal to C? Can...

I am studying Obversion for the first time in terms of Venn Diagrams. I'm am struggling to understand the conventions. Obversion requires two steps: (1)The quality must be changed. (2)The predicate is replaced with it's complement. Before I go on, I want to point out two types of...

Hi everyone, I've got a test tomorrow, and I've no idea how to do this question; http://server5.uploadit.org/files/itsallgood-help.JPG If someone could please do a step by step guide how to do this, it would be great. Thanks very much. :smile:
