Math Problem Statement
which would be used in this PPI or BPI: Consider the weighted voting system [51: 30, 30, 30, 10]. Write a few sentences explaining to a friend who hasn't taken this class why it might not make sense to say that Player 4 has 10% of the power in this system even though they have 10% of the votes. You can assume that your friend understands how a weighted voting system works.
