She has 4 spots available.  The first spot can be filled by any of the 4 pots, so there are 4 possibilities for first place.  Now, the second place can be filled with any one of the 3 remaining pots.  The second-last and last places can be filled by 2 and 1 pot respectively.

The total number of ways is

4 x 3 x 2 x 1 = 24
