Google sheet select rows of paid where open and paid are there and open only and paid only

I have a Google sheet with about 10000 rows . It's has invoices which are marked as paid and open. Many of them are marked as paid in one row and open on another row (same invoice number). I want to extract only the paid invoices , which also have an open entry and the open invocies which have no paid entry. Also select where paid only is there.
