What are the states and names of all colleges that didn't accept students in the tryout decision?
select state, enr from college where cName not in  ( SELECT DISTINCT T1.cName FROM college AS T1 JOIN tryout AS T2 ON T1.cName   =   T2.cName WHERE T2.decision  =  "yes" ) 
states refers to state; names of all colleges refers to cName; didn't accept students in the tryout decision implies filtering colleges where their decision was not 'yes' in the tryout;
