Preliminary:
Permutations are different arrangements or sequences that are formed from part or all of the objects.
The formula for permutations without double elements is P = n!
The formula for permutations with multiple elements is P = n!/k!
The formula for cyclical permutations is (n – 1)!
...................................
A combination is a collection of some or all objects regardless of their order.
The formula for the combination is C(n, r) = n!/(r! (n – r)!

Answer:
12 word order
Step-by-step explanation:
"TREE"
t = 1
r = 1
e = 2
[tex]P = \frac{n!}{k!} [/tex]
[tex]P = \frac{4 \times 3 \times 2 \times 1}{2 \times 1} [/tex]
[tex]P = \frac{24}{2} [/tex]
[tex]\boxed{\tt {{\colorbox{pink}{P = 12 \: word \: order}}}}[/tex]
