If A = {x : x is the name of a month}, what type of set is A?
Answer and explanation
Correct answer: Finite set
The names of the months in a year are January through December, giving exactly twelve distinct elements. Since the number of month names is fixed and limited, A is a finite set. It is not empty because month names exist, not infinite because there are only twelve of them, and not a singleton because a singleton has exactly one element.
