(Q). In how many ways two identical kings can be placed on a 8×8 chess board such that they are not on adjacent squares?
Solution:- From the solution of previous question number of ways = 3612 (When kings are distinguishable)
now in this question kings are indistinguishable i.e. we can not differentiate between kings because both kings are identical.
So this will half the count of the previous question to get the result.
Hence final answer is = 1806 Answer
