Application Express :: Select From Several Tables

i have 3 tables in my database..

table1 with one column

table1
table1_id
11
12
13
14

table2 with one column

table2
table2_id
21
22
23
24

table 3 with 2 primary foreign keys from table1 and table2

table3
table1_id table2_id
11 21
11 22
12 23
12 24
13 21
14 22

i want a select statement that selects all from table2 where the specified table1_id is not in the list of the table1_id in table3

for example if i want the list for id 11 it should return (23, 24)

i came up with the following but it didn't work

select table2_id
from tabel3 c, table2 b
where table1_id <> 11 and c.table2_id = b.table2_id

i know my explanation is not that clear..
