On (A={2,4,6}), (R={(a,b):a \le b}). Why is (R) reflexive?

Answer and explanation

Correct answer: Because every (a \le a) is true

Step 1: Reflexivity checks whether each element is related to itself. Step 2: For every number, (a \le a) is true, so ((a,a)) is included. Step 3: Be careful about the difference between (<) and (\le).
