VTU 4th Sem Maths | Counting with Repeated Elements|Module 4 |Arrangements with Restrictions BCS405A

In this video, we solve a VTU 4th Semester Maths problem from Module 4: Principles of Counting – Part 2. 📌 Question: In how many ways can 5 A’s, 4 B’s, and 3 C’s be arranged such that all the individual letters are not in a single block? We apply the concept of permutations of repeated items and use complementary counting to find the number of such arrangements where A's, B's, and C's are not grouped together as blocks. This is a frequently asked problem in exams and helpful for understanding permutation logic under constraints.
