Recall / Warm-Up

These problems review set notation and membership from earlier work.

Is the set $F = \{\text{days of the week}\}$ a finite set or an infinite set?

Finite — it has exactly 7 elements, which you can count.

Infinite — the days keep repeating week after week.

Neither — a set of days cannot be measured.
