Hi All

The probability questions in OG are fairly easy ..
Could some one guide me if one should be doing tougher problems than those given in OG if you are tragetting 700+ or will OG suffice.
I am practising both 12th edition and 10th edition !

Questions on probability to practice:
DS: search.php?search_id=tag&tag_id=33

Hard questions on combinations and probability with detailed solutions: hardest-area-questions-probability-and-combinations-101361.html

In addition, note that usually the GMAT combination/probability questions are fairly straightforward and as practice shows you won't encounter more than 2-3 questions from this field.

Hope it helps.

It might be a good idea for you to check out the Veritas Combinatorics and Probability book. It covers the GMAT relevant theory of these topics and provides you with many higher level questions.
