Today we are going to review the proposed problems and solved exercises on permutations and combinations in combinatorial analysis. ✔ All videos on the topic: • Combinatorial analysis: permutations ... Today we are going to review many combinatorial analysis problems, we are going to use combinations and permutations. We will treat variations as a case of permutations. The difference between permutations and combinations is that in permutations the order of the elements matters, and in combinations the order does not matter. We are going to start by reviewing the definitions and theory, and then we are going to solve many problems. The problems are grouped by difficulty levels, there are easy, intermediate and difficult ones. We will solve many combinatorial analysis problems, using combinations, permutations and variations. __________________________________________________________________ ✔ Subscribe: https://goo.gl/3HP9QH (don't forget to give it a like ????) ✔ Download the exercise guide: https://matemovil.com/?p=3536 ✔ FACEBOOK: / matemovil ✔ INSTAGRAM: / matemovil2 ✔ TWITTER: / matemovil1 ✔ Become a sponsor: https://goo.gl/9mrmg9
