Two 4-sided dice are tossed and the sum of the down sides noted. A 4-sided die doesn’t have an “up” face like a 6-sided die has, so the down side is used

a. Determine the expected value of the sum.

I might be complicating this question. But wouldn't the expected value be 1/16?

E(X)=np

E(X)=1 X 1/16=1/16
