For all those who are unable to identify whether the question is to be solved by permutation ie arrangement or combinations ie selection.

This document explains all these concepts in a simplified manner..

I found this document while surfing web.....The credit entirely goes to the guy who has created this document..

Dear All,

I have always had problems with combinatorics, probability. How can I cope with these? What literature would you advise to read to eradicate this problem of mine?

Look at these: combination-and-probability-references-if-you-have-56486.html
https://magoosh.com/gmat/2012/gmat-permu ... binations/
permutations-and-combinations-simplified-150835.html
permutations-combinations-probability-download-questions-57156.html

The above links have all the theories related to permutations/combinations and probability.

I think you are giving up without giving it a proper shot. Maths does not come without practicing. Go over the theory first and then go for sub 600 questions in these topics. Once you understand those, move onto 600-700 and 700+ level questions. Use the GMATCLUB 'tag' feature for this (viewforumtags.php)

Thanks Engr2012,

These seem valuable sources.
Mm, sure, I intend to get the sense of these topics rather than learning related rules "by default". That's why i applied for your assistance :)

Regards,

Also, do solve questions on permutations, combinations and probability from the official guide. Link to all questions from OG is at the-official-guide-quantitative-question-directory-143450.html

Download the excel file saved at the-official-guide-quantitative-question-directory-143450.html#p1194024 . This file details all the quant questions tagged by difficulty and sub sections.

Feel free to post a question that has not been posted before and the experts will be more than happy to help.
