    the symbol U is set union so in that venn diagram for A U B' it means A or NOT B

    that upside down U is set intersection... so in that venn diagram for A upside down U B' it means A AND NOT B.

    AND is both we have to take A and NOT B into consideration. We can't drop one of them

    hmm I know if I do sets... like numbers A = 1 2 3 B = 1 2 A U B is 1 2 3 which is all the elements if A upside down U B then it's what do they have in common and that's just 1 and 2 Oh I see what the problem is ... isn't that for NOT B or NOT A the outside of the circle gets shaded or something

    A U B' is A or NOT B so the circle A is shaded the outside part of B is shaded

    venn diagrams are unique... they don't share the same picture.

    |dw:1437472598710:dw| that's the intersection one of A AND NOT B (only something in common is shaded) |dw:1437472632510:dw| that's the union. A OR NOT B (so shade everything that's being considered. A is shaded and NOT B is shaded)

    I guess.. I drew these before and I'm doing them again for the upcoming semester. I was always a huge fan of the U problems... like A U B is A OR B

    so anything to do with NOT is shade outside. like for the NOT B we don't shade the circle, we shade around the circle (outside - borders)
