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}
-A'

-A'
A)finite
B)infinite

Quizplus · Accepted Answer

A' is the complement of A, which consists of all positive integers less than or equal to 50. Since this set is finite and A' is its complement, A must be infinite.
