Statistics for Data Science 1 - W5_Tutorial 1

Welcome to Week 5 Tutorial 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 In this tutorial, we explore the Counting Principle through an engaging problem on permutations. Using the word “GRAPH”, we determine its dictionary (lexicographical) order and find the 73rd word in the sequence. Step by step, the lecture walks through how to apply permutation logic, analyze arrangements, and use counting techniques to arrive at the correct result. This tutorial emphasizes systematic problem-solving and strengthens your understanding of arrangements and combinatorial principles in practical scenarios.
