SAT Math: More Listing and Counting Problems

Last year, we wrote a post about Listing and Counting problems.  This type of problem isn’t as common as those that deal with functions or special right triangles, but if you want to maximize your score, you should know how to do these.

Below are six more problems that will give you some practice on these problems.  The answers appear at the bottom of this post.
