When describing the possible outcomes of tossing several coins, the source distinguishes between an overall property, such as the total count of heads and tails, and the detailed order in which they landed. What does it call the overall property?
AAn overall property called a macrostate
BA detailed order called a microstate
CA single measurement called a wavefunction
DA running total called a distribution function
Answer & Solution
Correct answer: A. An overall property called a macrostate
1. When counting coin-toss outcomes, the source separates the overall count of heads and tails from the exact sequence in which they occurred.
2. It names the overall count, without regard to order, an overall property called a macrostate.
3. Wavefunctions and distribution functions are not terms the source introduces in this coin-toss discussion, ruling out options C and D.
4. The detailed order itself is given a separate name, a microstate, which is a different concept from the overall property being asked about here, ruling out option B.
