I think I have it figured out but at the same time it's not making sense when I get to the end number.
Basically I'm trying to figure out the total number of choices you can make. Here's a picture that will either help you or confuse you.
I think it's as simple as doing 6 x 5 x 6 x 5. This equals out to 900 but there seems to be something missing and 900 looks a bit small compared to what I figured.
Since I don't know if I completely made it clear what I am trying to do I'll give an example.
If you take 1 from the first column, 1 from the second, 1 from the third and 1 from the last that will equal one choice.
Then if you repeat the above but in the fourth table choose 2 that's 2 choices, and so on and so on.
Help would be great if anyone knows anything. Thanks!
