How many ways can 3 students be arranged in three chairs? I'm not really sure but I think that the answer will be 9 (nine), is that correct..?

  1. No, it is 6 ways.

    Think it through this way:
    The first chair can be filled in 3 ways, for each of those the second chair in 2 ways, leaving only one way to fill the 3rd chair.
    So ...
    3x2x1 = 6
