Question

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 statements are true for rows A and E? Check all that apply. p ↔ q p ↔ r q ↔ p q ↔ r r ↔ p r ↔ q

Answer 1

Answer:

r--(pvq)

Step-by-step explanation:

just did the review

Answer 2

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 are the final answer as shown in the attached picture.
