Statistics for Data Science 1 - W5_L1: Permutations & combinations - basic principles of counting

Welcome to Week 5 Lecture 1 of the course "Statistics for Data Science - I" by Prof. Andrew Thangaraj. Full Course: https://study.iitm.ac.in/ds/course_pages/BSMA1002.html Video Overview This lecture introduces the fundamental principles of counting, which form the basis for understanding permutations and combinations in probability and statistics. You’ll learn how to quantify uncertainty and explore key probability rules such as the sum rule and product rule through simple, practical examples. The session also highlights how counting principles help calculate the number of possible outcomes and make data-driven decisions in uncertain situations. This lecture lays a strong foundation for more advanced topics in probability and statistical analysis.
