Question

solve the both think and discuss question please
it is urgeng

Answer 1

First of all disjoint set means that the sets have no elements in common.

In the 1st think and discuss
A-B refers to the set containing elements that belong to A only and not B
and B-A refers to the set containing elements that belong to B only and not A
whereas A intersection B refers to the set containing elements of both set A and B
from this description we can know that those are disjoint sets

In 2nd think and discuss
It says to sets are disjoint so they don't have any common element.
Thus their intersection will have nothing or will be a null set....
