The ballot just described is depicted at right. Since there are five elections and two choices in each election, a voter can cast the ballot in any of 2 2 2 2 2 = 32 possible ways, if she casts a legal vote for each election. In information-theoretic terms, her ballot conveys 5 bits of information concerning her value-preferences. (Mathematically, 32 = 25, and 5 = log2 32.) |
