CK-12's Probability and Statistics - Basic (A Full Course) is an introduction to theoretical probability and data organization. Students learn about events, conditions, random variables, and graphs and tables that allow them to manage data.
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.
