Mentioned is the link to one of our Counting (PnC) sessions. This is a 3.5 hours session which is a part of a 7-hour Counting class spread over 2 days.

This miscellaneous topic is one of the concern areas for most students. You may initially watch just an hour or so of the video recording. If it interests you, I suggest you watch the entire recording. This will change your conventional & formulae based perception (nPr, nCr) to PnC which you have been carrying since your school days & hence revolutionize your entire approach towards the topic.

Recording of a 2-hour class from our 9-hour CR module that would help you to understand not only the intricacies of CR but also the practical approach to tackle/attack questions; something we never find in the theoretical explanatory answers given in the books.
