Answer
$M \cap N = \emptyset$; M and N are disjoint sets.
Work Step by Step
The symbol $\cap$ represents intersection of sets.
The intersection of sets M and NR is the set that contains the common elements of M and N.
M and N have no common elements.
Thus, $M \cap N = \emptyset$.
Two sets that have that have no elements in common are disjoint sets.
