Question: Calculate the average players out in the first innings per match. How many of them were out by the leg before wicket?
SQL: SELECT CAST(COUNT(T1.Player_Out) AS REAL) / COUNT(T1.Match_Id), SUM(CASE WHEN T2.Out_Name = 'lbw' THEN 1 ELSE 0 END) FROM Wicket_Taken AS T1 INNER JOIN Out_Type AS T2 ON T1.Kind_Out = T2.Out_Id WHERE T1.Innings_No = 2
