Please help.
I spent a lot of time during my GMAT preparation studying probability, permutation, and combinations. I regret spending so much time on these subjects because I ended up seeing only 1 permutation question on the actual exam. The fact is that these "difficult" questions appear infrequently on the GMAT.
My recommendation to you is not to overemphasize these topics. These guides should provide you a decent overview:

I recommend that you also sign up for the free Delta Course problem-a-day e-mails. Delta Course will send you a permutation/combination/probability question each day and provide you the answer the following day:

If you still think that you need further study on these subjects, maybe you should sign up for Delta Course content access. It's $27 and it will prepare you thoroughly for these kinds of questions on the GMAT.
Best of luck!
