I've noticed when taking CAT's and when doing problems in study guides I can't seem to grasp probability and permutation/combination problems (more perms/combs than probability).
I've gone through the PR, OG11, and OG Quant already. These books don't seem to cover that many of these type of problems.
Can anyone recommend a specific book, website, etc...to help?
Thanks,

What I've found best is after going through the problems, just sit back and really look at the problem and figure out what is going on. Don't just think that by seeing the walk through you will understand it. Figure out why the formulas are what they are and it will be easy for you.
