Execution Permission Denied

I've just downloaded and installed sql server. I have created a table using query


create table student
(st_id int,
st_name varchar(20));


but on execution received msg


Msg 262, Level 14, State 1, Line 1
CREATE TABLE permission denied in database 'master'.


What should I do now?
