Entropy & Information Flow. Consider the instruction x:=y+z, which takes a system from state s to state t. Assume that x does not exist in state s, and the probability distributions of y and z are as follows: - y=0 with probability of 1/3, or 1 with probability of 2/3 - z=1 or 2 or 3 with equal probability
