Estimated Rows

SELECT TOP 10 gs.value FROM GENERATE_SERIES(1, 10) AS gs ORDER BY NEWID () OPTION (RECOMPILE); go DECLARE @a int = 10; SELECT TOP (@a) gs.value FROM GENERATE_SERIES(1, @a) AS gs ORDER BY NEWID () OPTION (RECOMPILE);In the actual query plans, what is the estimated number of rows for each batch?
