Sorry, don't have any help for you here, but....

speaking of this problem, does anyone know of a good text or other resource for studying problems like these? I've heard Delta course is good, but that seems like overkill. All one really needs is a lot of practice problems, but I haven't found anything like that yet.

Any help?

Much appreciated.

For same-size different-color, number of combinations = 4c3 * 2
For same-size same-color, number of combinations = 4 * 2

Total = 16.

Is it C?
