Executive board?

Question

A soroity has an executive board consisting of a chair, vice chair and 3 other members. Its voting rules indicate that an issue can pass in 2 ways: if the chair, vice chair and one other member support the issue or if one of the chair or vice chair and 2 other members support the issue. Explain why this is a weighted voting system.

Answer 1

because, the three others cannot win over the other three, and if the chair does not support it, then the two vice chairs cannot overthrow the judgement without other support.

Answer 2

The chair and vice chair cannot be outvoted by the other 3.
