Hello everyone, it's Chill Physics again! 😎 After a while of waiting, we've finally completed another math video. This video is about: Permutations - Combinations - Arrangements (10th grade math). We've put a lot of effort into explaining the nature of these three concepts and combining them with vivid illustrations. We hope this video will help you enjoy the theory of combinations even more. Also, because the video is quite long, we couldn't cover everything taught in the textbook. Therefore, there will be more supplementary videos in the future to fill those gaps. Stay tuned! 💕 P/S: Thank you very much 😊 #math #mathematics #mathgrade10 #mathematicalthinking –––––––––––––––––––––––––––––– 🌟TIMELINE: 0:00 Topic of today's video 0:24 "Learning to Count" and basic counting examples 01:12 How many ways are there to put together an outfit? 02:40 The problem of seating 3 people in 3 seats 03:30 The problem of seating 4 people in 4 seats 04:05 The number of ways to seat n elements in n positions (general) 04:46 Permutations and n factorials (n!) 05:23 Permutations of 0 elements 05:52 The problem of seating n elements in 3 positions 06:28 The problem of seating n elements in 4 positions 06:49 The number of ways to seat n elements in k positions (general) 07:02 Permutation formula 07:33 The mathematical relationship between permutations and combinations 08:33 Combinations and tree diagrams 09:44 Combinations and distinct order 11:12 Combinations and non-distinctive order 12:38 Combination formula 14:02 Summary of combinations and combinations 14:25 Practical example 1: Creating a password 16:29 Practical Example 2: Playing Lottery –––––––––––––––––––––––––––––– 🔊 License: 🎵 Faithful Mission (Prod by Artificial Music) Source:    • Faithful Mission   Artist:    / @smarttoaster   🎶 Imagine (Prod. by Lukrembo)    • lukrembo - imagine   ––––––––––––––––––––––––––––––– 📧 Contact: [email protected] (Duy Nguyen) © Copyright belongs to Physics Chill © Copyright by Physics Chill ☞ Do not Reup
