Plz anons, recommend good resources for mastering combinatorics and probability, right from scratch. It can be videos lectures, books, etc., I just wish to get an intuitive hang of the basics and advanced topics(undergrad level) and possess the confidence & ability to tackle hard problems. I have about 30-40 days of free time btw, something which I totally wish to dedicate for this. Btw, I only know basic coordinate geometry(eqns of straight lines, circles, conics, 3d lines & planes). basic high school algebra like quadratic eqns, arithematic-geometric progressions, binomial theorem and basic calculus.
I did try studying basic permutations on my own using a standard math textbook followed by high schools in my cunt, but it's dry, boring and seems to have little to no explanations & reasoning as to why shit just werks, which is understandable as permutations and combinations is just one of the 15 or so many chapters in that book
