Mathematics : "Do you need some help in math?"

 Hello everyone, my name is Andrea and I'm studying mechanics and industrial automation at highschool. We live in a world in which everything is controlled by mathematics. Unfortunately is EVERYWHERE so if you need some help I'm here, leave a message if you want :)

I have been studying permutations and combinations for two months, but I still can't master it. I simply can't grasp the logic of permutations and combinations. I've always thought my approach was very logical. But I can't understand the answer. I've begun to wonder if I'm mentally challenged.
Could you help me with the problem of permutations and combinations?
