On a board game if you landed on red you move ahead 1 space,land on blue you move ahead 2 spaces,and land on orange you move back 1 space. If you took 30 spins where would you expect to land relative to where you started?

Hard to say. What other colors are there? How many of each color spaces are there? How is the spinner marked? If you're going to post a problem, make it complete, eh?
I say you land right back where you started. Disprove it.
