The truth table represents statements p, q, and r.

p q r
a t t t
b t t f
c t f t
d t f f
e f t t
f f t f
g f f t
h f f f
which statement is true for rows a, c, and e?

r → (p ∧ q)
r → (p ∨ q)
(q ∧ r) → p
(q ∨ r) → p

We have been given the truth table for three variables p, q, and r. as shown below

p q r

A T T T

B T T F

C T F T

D T F F

E F T T

F F T F

G F F T

H F F F

Now we need to find Which statements are true for rows A and E for the following statements:

p ↔ q p ↔ r q ↔ p q ↔ r r ↔ p r ↔ q

To find that we need to use table of P <-> Q as shown in picture.

We know that if both statements are true for P and Q then only P <-> Q will be true. So using that trick we see that only q<->r and r<->q
