How many members are needed for a quorum in a 9-member commission?

To determine how many members are needed for a quorum in a 9-member commission, it's important to recognize that a quorum is typically defined as the minimum number of members required to be present for the commission to conduct its business.

In most cases, a quorum is calculated as a simple majority of the total members. For a 9-member commission, a majority would be more than half of the total members. Since half of 9 is 4.5, rounding up means that at least 5 members need to be present for the commission to effectively carry out its responsibilities. This ensures that there is sufficient representation to make decisions, reflecting the views and interests of the commission as a whole.

Thus, the correct answer is that 5 members are necessary to achieve a quorum for a 9-member commission.
