#### Question

Prove that the following statement pattern is equivalent :

(p ∨ q)  r and (p → r) ∧ (q → r)

#### Solution

Truth table given is as follows:

 1 2 3 4 5 6 7 8 p q r A=p vv q B=p->r C=q->r A->r B ^^ C T T T T T T T T T T F T F F F F T F T T T T T T T F F T F T F F F T T T T T T T F T F T T F F F F F T F T T T T F F F F T T T T

Thus from column 7 and 8

(p ∨ q)  r ≡(p → r) ∧ (q → r)

Is there an error in this question or solution?
