How can I master Combinatorics and Probability Skills? [#permalink] New post   30 Dec 2021, 00:07
Hi guys and experts,

May I ask how can I master Combinatorics and Probability Skills?

I was studying the All the Quants - Combinatorics and Probability skills topic, but find it too simple.

Studying the cheat sheet page provided by GMAT Club at the following link, yet find it too difficult:
https://gmatclub.com/forum/permutations-and-combinations-simplified-150835.html

More importantly, when I studied the above materials together, I got confused...

I am weakest at the above topics, really want to know how to master such topics...

Could anyone please help?

Thanks a lot!

One thing that can help is to try to grasp the underlying concepts. Consider playing around with smaller questions to really get a feel for how and why you divide and multiply to get the answer you need. This same type of learning can be applied to different sub-topics, too, such as exponents. Instead of memorizing the rules regarding the formulas, you can play around with small numbers and see how things change and interact.
