Finding errors
Unfortunately I think I'm finding some errors and I'm only on the first lesson. For example; lesson one example 10 says the odds of rolling two dice and getting a sum of ten (denoted p(B)) is 1/36. This is wrong. It should be 3/36 as there are 3 out of 36 possible combinations that sum 10: 6,4 5,5 and 4,6.
This makes me question how well the book was reviewed as it's pretty obvious in the included figure. Will be downloading a different book.
Bad editing
With in the first few pages there are obvious mistakes. 2 is a prime number and the author clearly does not know this. The ideas are likely sound but, I would not trust the actual math behind the calculations.
