Part
1.
Indicate
whether
the
argument
is
valid
or
invalid.
For
valid
arguments,
prove
that
the
argument
is
valid
using
a
truth
table.
For
invalid
arguments,
give
truth
values
for
the
variables
showing
that
the
argument
is
not
valid.
(1)
Not
valid.
For
p
=
T,
q
=
F,
r
=
F
and
p
=
F,
q
=
T,
r
=
F:
these
two
combinations
prove
the
argument
invalid.
Part
2.
Converse
and
inverse
errors
are
typical
forms
of
invalid
argu-
ments.
Prove
that
each
argument
is
invalid
by
giving
truth
values
for
the
variables
showing
that
the
argument
is
invalid.
You
may
find
it
eas-
ier
to
find
the
truth
values
by
constructing
a
truth
table.
