Selecting from two tables

I have a table called Jobs and another called Applications. I can
query all Job rows, but how do I also include the number of Application
rows for each Job row in the SELECT statement?

applications has a jobid foreign key

create table job ( jobid SERIAL,
login varchar(40),
jobtitle varchar(70),
jobdescrip TEXT,
jobkeywords TEXT,
valid int2 NOT NULL,
postdate TIMESTAMPTZ,
PRIMARY KEY (jobid),
FOREIGN KEY(login) REFERENCES company
ON DELETE CASCADE
);

CREATE TABLE application ( applid SERIAL,
jobid INTEGER,
login varchar(6),
apldate TIMESTAMPTZ,
PRIMARY KEY (applid),
FOREIGN KEY (jobid) REFERENCES job
ON DELETE CASCADE,
FOREIGN KEY (login) REFERENCES
student
ON DELETE CASCADE
);

thanks for any help on this..
