Statistics for Data Science 1 - W5_L2: Permutations & combinations - factorials

Welcome to Week 5 Lecture 2 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 concept of factorial notation, explaining what it represents and how it is used in combinatorics and probability. You’ll learn how factorials help determine the number of possible arrangements or outcomes, using a simple race scenario as an example. The lecture also covers how to simplify expressions and represent products using factorial notation, building a strong foundation for understanding permutations and combinations. Get ready to explore one of the most essential mathematical tools in counting and probability theory.
