A bar chart about how many students are enrolled in colleges that have student accepted during tryouts, and in which states are those colleges?
SELECT state, enr FROM College AS T1 JOIN Tryout AS T2 ON T1.cName = T2.cName WHERE T2.decision = 'yes'
SELECT "state", "enr" FROM "College" "T1" JOIN "Tryout" "T2" ON "T1"."cName" = "T2"."cName" AND "T2"."decision" = 'yes'
