These are and 3 1 2.Īpproach : – Inclusion-Exclusion Principle is a combinatorial counting technique that allows us to count the number of elements in the union of multiple sets. įor i = 3, the total number of derangements is 2. To determine the number of derangements( or permutations) of n objects such that no object is in its original position (like Hat-check problem).Īs an example we can consider the derangements of the number in the following cases:įor i = 1, the total number of derangements is 0.įor i = 2, the total number of derangements is 1.

The values of the corresponding regions, as can be noted from the diagram are –īy applying Inclusion-Exclusion principle, ISRO CS Syllabus for Scientist/Engineer Exam.ISRO CS Original Papers and Official Keys.
