Permutation is the number of arrangements possible in a given condition where order matters. Mathematically, we can compute it as shown below.
[tex] P(n, r) = \frac{n!}{(n-r)!} [/tex]
Thus, given P(4, 4), the value pf the permutation is equal to
[tex] P(4, 4) = \frac{4!}{(4 - 4)!} [/tex]
[tex] P(4, 4) = \frac{(4)(3)(2)(1)}{0!} [/tex]
[tex] P(4, 4) = \frac{24}{1} [/tex]
[tex] P(4, 4) = 24 [/tex]
Thus, we have a value of 24.
Answer: 24
