Question

Given the following, determine the set (AUB)' intersects B. U= {1,2,3,...16} A={4,5,7,8,16} B={5,6,7,9} (AUB)' intersects B= ? I am super stuck.... any help??

Answer 1

do steps, now, {A U B } =?

Answer 2

I got {5,7} but it came up wrong. I only have one more chance to get it right

Answer 3

AUB= {4,5,6,7,8,9,16}
(AUB)'= {1,2,3,10,11,12,13,14,15}

Answer 4

yes,

Answer 5

{1,2,3,10,11,12,13,14,15} and {5,6,7,9} = {empty}

Answer 6

I can't figure out the intersection of B if it is not 5,7. That is what the Venn digram shows when I draw it out.

Answer 7

no need to use Venn, but if you want, it's ok.

Answer 8

so the answer is N?

Answer 9

I don't know what the terminology for empty set your professor prefer. If he used N, so use it.
