CREATE TABLE table_77038 ("Athlete" TEXT, "Event" TEXT, "100 m" FLOAT, "400 m" FLOAT, "110H" FLOAT, "1500 m" TEXT, "Final" FLOAT)

What was the 400m that had a 110H greater than 14.21, a final of more than 7838, and having result in events?
SELECT COUNT("400 m") FROM table_77038 WHERE "Event" = 'result' AND "110H" > '14.21' AND "Final" > '7838'
SELECT COUNT("400 m") FROM "table_77038" WHERE "110H" > '14.21' AND "Event" = 'result' AND "Final" > '7838'
