<p>does anyone know what a good book/source/method is to learn sat probablility and things like permutations, combinations, etc...?</p>
<p>barrons math iic has all that stuff - permutations, probability - but if you're looking to improve the regular sat math, try getting the barrons sat book (big, fat white book) if you're looking to LEARN the material + want practice doing that specific type of problem...</p>
<p>^^^ he's right</p>
<p>(s)he :) (10 char)</p>
<p>The only method that I think you need to know for SATI (from my experience) is the fundamental counting theorem (or something like that) and how to apply it to various types of problems.</p>
<p>practice, practice, and again practice!</p>
<p>what's the fundamental counting theorum?
(it wasn't even on wikipedia)</p>
<p>that's not the technical term ... sorry (counting principle i think)</p>
<p>If one event can happen in A ways, and another can happen in B ways, then there are A x B ways of doing both (provided that they are independent, meaning one's outcome does not affect the other outcome).</p>
<p>With the above and some logic (so you don't need combinations), you can solve any RED book problem and probably most blue book ones (haven't finished all the tests).</p>
<p>I'll post some problems that illustrate this from the math section if you want.</p>
