Permutation: A set of objects in which position (or order) is important.
So, we are talking about permutation.
total socks (P) chosen socks can be written as 10P8.
We now use the formula nPr = n!/(n - r)!, where n is the total number of objects and r is the number of objects chosen (what we want).
10P8 = 10!/(10 - 8)!
