Counting, Combinatorics, and Restrictions: Video

Combinatorics problems are feared mostly because no one teaches them properly in school.

When you learn simple methods to break these questions down, you’ll find them some of the easiest questions on the GMAT!

Strangely or not, there is an underlying logic to counting properly even if it’s not really what it would seem on the surface. More often than not, you’re simply multiplying everything together.

The main problem with this is figuring out exactly what to multiply, and when. This video shows how to apply restrictions to your multiplications to be sure that you’re doing the right thing.

This is a teaser video for our upcoming course on Probability and Combinatorics, released late 2015–sign up to the mailing list (that’s on the right side of your screen:) ) on this or any page to get more information about this course or GMAT tutoring in London and worldwide via Skype!
