Two students, Avani and Aaden, line up one behind the other. How many different ways can they stand in line?

Answer 1

If Avani and Aaden stand in line, there are only two possible ways they can stand.

If we consider all possible permutations of their names, Avani can stand in front of Aaden, or Aaden can stand in front of Avani.

Therefore, there are only 2 ways they can stand in line.
