But by principle of inclusion and exclusion we have included the arrangements in which any two of them has occupied their respective positions twice. So we have to subtract them once. So number of ways in which any two of them are at correct position is n 2 (n-2)! and so on. So the total number of derangements = n! - [n 1 (n-1)!-n 2 ...
