    step 1 Address the formula, input parameters & values
    n = 12
    k = 12
    Find what is 12 CHOOSE 12?

    step 2 Substitute n and r values in below nCk formula

    nCk = n!/k! (n - k)!
    12 CHOOSE 12 =12!/12! (12 - 12)!

    step 3 Find the factorial for 12!, 12! & 0!, substitute the corresponding values in the below expression and simplify.

    12C12 = 12!/12! (0)!

    =1 x 2 x 3 x 4 x 5 x 6 x 7 x 8 x 9 x 10 x 11 x 12/(1 x 2 x 3 x 4 x 5 x 6 x 7 x 8 x 9 x 10 x 11 x 12) (1)

    = 1/1
    = 1/1

    12C12 = 1
