Let U = {9, 10, 11, 12, 13, 14, 15, 16, 17, 18}, A = {10, 12, 14, 16}, B = {13, 17}, and C = {10, 13, 16, 17, 18}. List all the members of each of the sets. (Enter solutions from smallest to largest. If there are any unused answer boxes, enter NONE in the last boxes.)
A �¿ B �¾ C with a - over A �¿ B.
I came up with {10, 15, NONE.} Is this correct?
that should read A intersection B and union C
A ∩ B = ∅ or the null set
then ∅ ∪ C = C = {10,13,16,17,18}
your answer of {10,15 ,NONE } makes no sense, I don't see an element called NONE
To find the members of the sets A ∪ B ∩ C, let's break it down step by step.
Step 1: A ∪ B means the union of sets A and B, which includes all elements that are in either set A or set B (or both). So, A ∪ B = {10, 12, 13, 14, 16, 17}.
Step 2: A ∪ B ∩ C means the intersection of the set A ∪ B with set C, which includes all elements that are common to both sets A ∪ B and C. So, A ∪ B ∩ C = {10, 16}.
Therefore, the correct answer for A ∪ B ∩ C is {10, 16}.
