Set A is the set of birth dates of students in a class. If the class has 40 students, what kind of set will A be?
Answer and explanation
Correct answer: Finite set
There are only 40 students, so at most 40 birth-date entries can be collected. Some students may share the same birth date, which would reduce the number of distinct elements, but it can never make the set infinite. The set contains a limited number of dates and is therefore finite. Hence, option C, finite set, is correct.
