thanks guys, I pretty much had a panic attack this morning. I have no idea how I did, but the test appeared to be easier then the review sheet. although if I failed again(I got a 43 on my midterm) I think its the probability that would have broken me. I can do permintations and combinations, they are easy as pie, so are the money problems, and complex numbers. but I had a hard time with the probability I was so confused, because I could not remeber what to do. I think I did fine on the matrices exept for the one question on it solving for x and y useing matreces I could not even find how to properly do that in my notes who knows why, I remeber writing the notes on it and doing the questions lol but the only thing I could find regarding solving for x and y was without matraces. so lets just pary that I passed lol
