Answer:
789 voters
Explanation:
To determine the number of voters who voted for both propositions, we can use the inclusion-exclusion principle. The formula is:
Total votes = Votes for Proposition 1 + Votes for Proposition 2 - Votes for Both Propositions
In this case:
2171 total votes = 1332 votes for Proposition 1 + 1628 votes for Proposition 2 - Votes for Both Propositions
Therefore, 789 voters voted for both propositions.
