I have an exam on Wednesday on Permuations and Combinations and while I understand most of the concepts, I find it difficult to apply it to the questions because I haven't done many practice questions. I was wondering if someone had an excellent book on the topic that I could go through and understand permutations and combinations well.

do you mean counting exercises? – citedcorpse Jun 14 '13 at 17:00
@exitingcorpse I guess (?) What do you mean by "counting exercise"? – Jeel Shah Jun 14 '13 at 17:05
things like "if you're at a bakery that sells ten types of donuts, how many different dozen-packs of donuts can you buy" – citedcorpse Jun 14 '13 at 17:06
@exitingcorpse Oh right, yes, that's exactly what I'm looking for, for both combinations and permuations – Jeel Shah Jun 14 '13 at 17:09

I would highly recommend Probability and Statistics with Applications: A Problem-Solving Text by Asimow/Maxwell, along with its solutions manual. (You can find a link to both of these books here: .) When I was studying for the actuarial exam covering probability, I struggled with combinations and permutations until I found this book, which gives a good buildup of difficulty of combination/permutation problems. The solutions are (mostly) very clear in how the approach to each problem works.

Good luck!

Is there any other books that you may know of? This book is difficult to order currently. – Jeel Shah Jun 15 '13 at 12:53
You could try Probability for Risk Management by Hassett/Stewart, but it's not as good. – Clarinetist Jun 15 '13 at 17:08
