How many ways to go from A to B ? Lines, Pascal and Permutations

Can you solve the "how many ways" type of problem using Pascal triangle ? Do you know we can make an even simpler solution if we apply permutation ? Well, each problem is unique and that is why we need several tools, need to know so many exercises so we can apply the best solution for each particular exercise. On this video I will teach you how to apply Pascal Triangle for solving this problem in 4 different examples: ✔️ ex1) Simple grid; ✔️ ex 2) Grid where you have to pass by a specific point; ✔️ ex 3) Grid where you have CANNOT pass by a specific point; ✔️ ex 4) Grid where you have to pass by a specific PATH. Then I will show you a more complex grid, where applying Pascal will not be the best option. We will go with permutations. Here we will see 2 examples: ✔️ ex 5) Simple grid; ✔️ ex 6) Grid where you have to pass by a specific point. On this video we will: 1️⃣ Know how to apply Pascal triangle to solve how many ways to go from A to B; 2️⃣ Learn how to apply permutation to solve problems like that: much faster; 3️⃣ Practice 6 different exercises. 🔥 Content : 0:00 - What we will see on this video 1:03 - Firs method : Basic 1:40 - Second method: Pascal Triangle 2:50 - History of Pascal Triangle 4:56 - 1st Exercise: simple 7:40 - 2nd Exercise: Must pass thru C 10:38 - 3rd Exercise: Not thru C 11:40 - YOUR ANSWER here !!! 14:00 - 4th Exercise: Must pass thru a PATH 14:40 - Can you catch the MISTAKE ? 16:52 - 5th Exercise: Permutation method 19:21 - 6th Exercise: Permutations + Specific path grid 22:03 - A few words about ARISTOTHINK 22:44 - Thanks 🙏, subscribe 👍
