Put your answers on these sheets and turn them in along with any calculations you do on other pieces of paper. Be sure to put your name on all pages you turn in. This enables them to be decoded. The OR gate is irreversible. When we want to estimate the probabilities in a probability distribution, we can use the Principle of Maximum Entropy.
All probabilities are equal.
High -energy states are more likely to be occupied. Low -energy states are more likely to be occupied. It is necessary to anticipate the inevitable increase in entropy. It is never possible to determine what the inputs were from knowing the output. It is not always possible to determine what the inputs were from knowing the output.
