Astudent wants to demonstrate entropy using the songs on her portable music player. what should she do to demonstrate the lowest entropy? a. play a single song by a single artist b. play only the classical songs on shuffle c. play all the songs in alphabetical order d. play all the songs on shuffle

 A. play a single song by a single artist

Explanation: Entropy is the measure of randomness or disorder of a system.

A system that has more random distribution is considered to have more entropy and a system with ordered arrangement is considered to have less entropy.

Playing a single song by a single artist has least randomness , and lowest disorder and thus has lowest entropy.
