R.I. Gen. Laws § 7-1.2-806: Quorum of directors.

A majority of the number of directors fixed by or in the manner provided in the articles of incorporation or the bylaws, or by the shareholders or in the absence of a bylaw or shareholder action fixing the number of directors, then of the number stated in the articles of incorporation, constitutes a quorum for the transaction of business unless a greater number is required by the articles of incorporation or the bylaws. The act of the majority of the directors present at a meeting at which a quorum is present is the act of the board of directors, unless the act of a greater number is required by the articles of incorporation or the bylaws.
