(b) Use Eq. (31) to calculate the

change ASB of B. Use these results to calculate the total

ASA + ASB of the combined system in going from the initial situation where the

If the system A is isolated, it is overwhelmingly probable that its

increase (or, at most, remain unchanged) so that AS > 0. The answer to our

question is then simply that the desired decrease of randomness cannot be

achieved.
