Ok, this should be a simple one based on the problems I've seen resolved here, but simple or not, I don't remember the formula.
You have four levers, each can be set in two positions, what is the total number of unique lever configurations?
I was thinking (4x2)+(3x2)+(2x2)+(2x1)+(2x0), but that equals 20, and I can only come up with 16 configurations?
