Webn 1 (n-1)! 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 ... WebInclusion-Exclusion Rule Remember the Sum Rule: The Sum Rule: If there are n(A) ways to do A and, distinct from them, n(B) ways to do B, then the number of ways to do A or B is n(A)+n(B). What if the ways of doing A and B aren’t distinct? Example: If 112 students take CS280, 85 students take CS220, and 45 students take both, how many take either
