Permutation & Combination | Exercise 7.2 (Q#1–3) | Chapter 7 | 1st Year Mathematics

Alhamdulillah! In today’s lecture, we recorded another important class in which we started Exercise 7.2 of Chapter #7 – Permutation and Combination. 🔹 In this lecture, we covered: • Introduction to Exercise 7.2 • Revision of Permutation definition • Explanation of Permutation formula (nPr) • Real-life examples to understand permutation clearly • Exercise 7.2 – Question #1 • Exercise 7.2 – Question #2 • Exercise 7.2 – Question #3 🔹 About this lecture: 📌 Before starting Exercise 7.2, the concept of Permutation was explained in detail using simple real-life examples, so that students can clearly understand where and why permutation is used. 📌 This lecture is designed strictly according to Punjab Board syllabus and exam requirements. 🔹 Before solving questions, we clearly explained: • What is Permutation • Why order is important in permutation • Meaning of n and r in the permutation formula • When to apply permutation instead of simple counting • Common mistakes students make while using nPr 🔹 Concept explanation method: • Concepts were first built using daily-life situations • Formula of permutation was derived and explained step by step • Each question was analyzed before applying the formula • Proper reasoning was developed for correct selection of n and r • Complete mathematical working was shown • Board-style presentation was followed throughout 🔹 Key features of this lecture: ✔ Strong concept building ✔ Real-life based explanation ✔ Step-by-step solutions ✔ Exam-oriented approach ✔ According to Punjab Board marking scheme 📌 Questions #1, #2, and #3 of Exercise 7.2 are very important from the board point of view, and this lecture will help students build a strong foundation for upcoming questions of permutation. 📺 Like, share, and subscribe to Mathematics with Furqan Ali for concept-based and exam-oriented Mathematics lectures.
