it's a permutation of 6
the answer would be 6! = 6*5*4*3*2*1 = 720 times
6! is read as six factorial and to solve a factorial for exemple if we have n!.. the general rule to solve it is :
n! = n*(n-1)*(n-2)*(n-3).......*3*2*1 ad you'll get the answer

As the others have said, this is a permutation because you are putting the plants in ORDER. Think of it this way.
There 6 ways to put the first plant, 5 ways for the second plant, etc. Using the counting principle we get 6 * 5 * 4 * 3 * 2 * 1 ways, or as someone else has said 6! ways. The answer is 720 ways.

This is a permutation of 6.
This means that to find the answer you must do:
6*5*4*3*2*1
This gives you 720

Thats a permutation.
If you have 6 items, they can be rearranged 6! times.
6! is prounounced six factorial and simply means 6*5*4*3*2*1.
Which happens to equal 720.
