I am trying to learn Probability and Statistics on my own, and I find it very difficult with this book.

The book does do somethings well. It does explain concepts better than what I have read so far (Schaum's). However, in the sections on combinatorics, especially, and thereafter I cannot follow the logic. I read an example problem, the solution is given immediately with little explanation as to how. The author says the bare minimum e.g. here n=52 and k=13. I have seen the combinatoric calculations, that are the solutions, in a multitude of ways, with sums in the numerator, products in the numerator, and it is not at all obvious as to why. There is insufficient discussion in the solution.

Then in working the exercises, there is nonuniform quality with the even-number solutions. Some answers just have a number, others have the formula, and some have numbers with factorials so you can kind of guess what the author did. But in the case where there is just a number, you can't.

Can you learn from this book? Sure you can, but my prediction (after reading Ch. 1) is that it's about as difficult as trying to learn a programming language by looking at syntax and running the code, having no programming experience.
