Questions using plurality

Problem 1

Why can a plurality winner lack a majority?
Answer and explanation

Plurality compares an option with each rival individually, while majority requires more than half the relevant total. In the supplied 45–35–20 example, 45 is the largest count but less than 51, so it meets the first condition and not the second.

Problem 2

Invented election: Candidate A receives 45 votes, B 35, and C 20; all 100 votes are valid; the stated rule is plurality. A commentary calls A’s result a majority endorsement of every campaign proposal. Correct the commentary and qualify what can be inferred.
Answer and explanation

A wins under plurality because 45 is greater than 35 or 20. A receives 45 percent, so the result is not a majority of valid votes. The election selects an officeholder; it does not reveal each voter’s reason or independently approve every proposal. Additional survey or issue-specific evidence would be needed for those claims, and turnout would require a separate eligible-population denominator.

Apply the plurality rule.

Calculate 45/100.

Separate candidate selection from issue-by-issue preferences.

Response criteria

  • Explain the relevant institution or economic concept accurately; show correct calculations where needed.
  • Connect supplied evidence and stated assumptions to an explained conclusion.
  • Compare feasible options and their effects on different people without stereotypes.
  • Identify a limitation, tradeoff, uncertainty, or condition that qualifies the conclusion.

Problem 3

Invented vote: A 40, B 35, C 25 out of 100. Calculate A’s share and state whether it is plurality or majority.
Answer and explanation

A has forty percent and a plurality because 40 exceeds each rival’s count. It is not a majority because it does not exceed half. A different rule requiring a majority would need further procedure; second preferences are not supplied.
