Permutation and Combinations, Probability

by crak.gmat » Thu Sep 18, 2008 5:26 pm
Permutation and combinations, and Probability are my weak areas in Q. OGs don't cover complex problems in these areas, so was wondering if anyone here can point me to links or materials (or problems w/ solutions) where this topic is covered at a greater detail.

Appreciate your help in advance.

Thanks!!

crak.gmat,
I am right there with you. It's a tricky concept as it has more variations than other problem types.

https://beatthegmat.blocked/2005/08 ... d-790.html

Check out this page that has various links to permutaions/comb/prob and others.


Other thing I would do is get exposed to various problem types from book u may have and escpecially this forum(u can search the archives for these problem types). There are so many prob/perm/comb questions on this forum

Also there are many subject matter experts on this forum who have posted answers to a lot of these questions. Look through them and try to understand their thought process and explanations.


Thats about it!! Good luck!

here's one of my favorites from another forum:

the next edition of our word translations strategy guide is going to hit shelves in a couple of months; it will feature newly expanded and improved sections on probability and combinatorics.
