Statistics for Data Science 1 - W5_Tutorial 6

Welcome to Week 5 Tutorial 6 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 tackle a fascinating letter arrangement puzzle involving all 26 letters of the alphabet (A–Z) under specific constraints. The problem explores how to sort the alphabet when certain conditions must be met — such as ensuring the first letter is a vowel, maintaining positional relationships between ‘A’ and ‘B’, and determining how the 26th letter influences ‘A’s position. Step by step, the lecture walks through the factorial calculations, permutation logic, and constraint reasoning behind this complex problem, demonstrating how even simple conditions can significantly change the number of possible arrangements.
