Determine whether the given set is finite or infinite. Consider the set N of positive integers to be the universal set, and let
A = {n ∈ N| n > 50}
B = {n ∈ N| n < 250}
O = {n ∈ N| n is odd}
E = {n ∈ N| n is even}
-B $\cup$ E

O = {n ∈ N| n is odd}
E = {n ∈ N| n is even}
-B $\cup$ E
A) finite
B) infinite

Quizplus · Accepted Answer

A is infinite because there are infinitely many positive integers greater than 50. B is finite because it contains all positive integers less than 250, which is a specific, countable number. O is infinite because there are infinitely many odd numbers. E is infinite because there are infinitely many even numbers.
