$A = (0, 8, 9)$ , $B = (1, 2, 3)$

Step 1

Set up the intersection notation of set ${1, 2, 3}$ and ${0, 8, 9}$ .

${1, 2, 3} \cap {0, 8, 9}$

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 two sets share no members, therefore the sets are mutually exclusive.
