myininaya · Answer

interestion means what they have in common what do both sets have in common

myininaya · Answer

if they have nothing in common, then you write its the empty set or you can use the notation for the empty set because i can't do the symbol here

anonymous · Answer

$$\{\} or  \emptyset$$ is the empty set.
