We have the following two transac- tions: Tl: BEGIN TRANSACTION Sl: UPDATE Xbox Games SET price=22 WHERE name%3' ok_game' S2: INSERT INTO Xbox_Games VALUES ('Another_Game', 0) S3: UPDATE Xbox_Games SET price=38 WHERE name='ok_game' COMMIT; T2: BEGIN TRANSACTION sS: SELECT AVG (price) AS average_price FROM Xbox_Games COMMIT; Above two transactions are hitting the DBMS roughly at the same time. What are the possible values for average-price?

What are the possible values for average price 

5. Consider the following table Xbox_Games(name, price) and assume that these values already exist in the
database ('ok game', 30), (good.game', 40), ('AWESOME.game', 50). We have the following two transac-
tions:
Tl: BEGIN TRANSACTION
Sl: UPDATE
Xbox_Games SET price3D22 WHERE name-="ok_game"
S2: INSERT INTO Xbox Games VALUES ('Another_Game'
S3: UPDATE Xbox_Games SET price-38 WHERE name-'ok_game"
COMMIT;
T2: BEGIN TRANSACTION
sS: SELECT AVG (price) AS average_price FROM Xbox_Games
СOMMIT;
Above two transactions are hitting the DBMS roughly at the same time. What are the possible values for
average-price?
