In how many ways can the 19 members of a chess club fill the offices of king, knight, bishop, and rook?

Solution:

This problem is a permutation because the order matters here. This means that choosing A as King, B as Knight, C as Bishop and D as Rook results in a different arrangement from B as King, A as Knight, D as Bishop and C as Rook. We would count them both because in the first case A is King, but in the second case A is Knight.

Therefore, the possible number of ways are given below:

Hence there will be 93024 ways 19 members of a chess club fill the offices of King, Knight, Bishop, and Rook.
