step 1 Address the formula, input parameters and values

__Formula:__

nPr =n!/(n1! n2! . . . nk!)

__Input Parameters & Values:__

Total number of alphabets (n) & subsets (n1, n2, . . nk) in the word "USA"

n = 3

Subsets : U = 1; S = 1; A = 1;

n_{1}(U) = 1, n_{2}(S) = 1, n_{3}(A) = 1

step 2 Apply the input parameter values in the nPr formula

= 3!/(1! 1! 1! )

= 1 x 2 x 3/{(1) (1) (1)}

= 6/1
