One is really straightforward: Since Z = 2 − Y, then ρ Y Z = − 1. The others I am not sure about. This is my attempt: We define X 1 to be the result of the first toss and X 3 to be the result of the third toss (they get 1 when heads). Then Y = X 3 + X − X 1. We therefore have that floating slough pump
