CREATE TABLE player (pid DECIMAL, pname TEXT, ycard TEXT, hs DECIMAL)

CREATE TABLE college (cname TEXT, state TEXT, enr DECIMAL)

What are the states of the colleges where students who tried out for the striker position attend?
SELECT T1.state FROM college AS T1 JOIN tryout AS T2 ON T1.cname = T2.cname WHERE T2.ppos = 'striker'
SELECT "T1"."state" FROM "college" AS "T1" JOIN "tryout" AS "T2" ON "T1"."cname" = "T2"."cname" AND "T2"."ppos" = 'striker'
