That's an amazingly precise number, thank you again. Then what about the average unit price of Latin and Pop?
SELECT AVG ( UnitPrice )  FROM GENRE AS T1 JOIN TRACK AS T2 ON T1.GenreId   =   T2.GenreId WHERE T1.Name   =   "Latin" OR T1.Name   =   "Pop"
average unit price refers to AVG(UnitPrice); genres Latin and Pop refers to WHERE T1.Name = 'Latin' OR T1.Name = 'Pop'; joining tables for genres and tracks refers to JOIN TRACK ON T1.GenreId = T2.GenreId;
