The set of all sets of exactly three integers are finite set, countably infinite set, and Uncountable.
A set is simply an organized collection of distinct objects forming a group and can be expressed in set-builder form or roaster form.
Let A= [2,3,4] = uncountable
B= [3,4)=uncountable
A ∩ B ={3}= finite
Hence,A ∩ B is finite set .
Let A= set of positive real numbers that is Uncountable.
B= Set of negative real numbers and positive integers that is Uncountable
Now, A ∩ B =Set of positive integer numbers
A ∩ B =countably infinite set.
Let A= set of real numbers that is Uncountable
B= Set of irrational numbers that is Uncountable
Then, A ∩ B = set of irrational numbers is Uncountable.
when A is a set of real numbers and B is a set of irrational numbers.
