<p>Hey guys,
I struggle the most with permutation and combination problems on the SAT and I was wondering if anyone knew a source of practice problems for me to work on...
Thank You!</p>
<p>No idea about a source of practice. The easiest way is to just use nPr and nCr on your calculator. The total number goes first, the number selected goes after. If order matters, use nPr. If order doesn’t matter, use nCr.</p>
<p>Hope that helps.</p>
