SQL & PL/SQL :: Oracle Query For Days Output

I want to pull out the output only when Day is 1 and 2 and 3. I don't want if either Day is 1 or Day is 2 or Day is 3 is present.

Test Case

--Creat Table
create table dummy_name
(name varchar2(5) not null,
day number(3) not null);

--Insert Values
insert into dummy_name values ('A', 1);
insert into dummy_name values ('B', 2);
insert into dummy_name values ('C', 3);
insert into dummy_name values ('B', 1);
insert into dummy_name values ('B', 2);
insert into dummy_name values ('C', 1);
