Find the Set Complement A \ B

$A = (1, 2, 3)$ , $B = (6, 8, 7)$

Step 1

Set up the intersection notation of set ${1, 2, 3}$ and ${6, 8, 7}$ .

${1, 2, 3} \cap {6, 8, 7}$

Step 2

The intersection of two sets is the set of elements which are in both sets. The intersection in this case is an empty set.

${}$

Step 3

The complement of the two sets is the remaining members of ${1, 2, 3}$ that aren't members of the intersection of the two sets.

${1, 2, 3}$
