Which one of the following is the most appropriate logical formula to represent the statement? "Gold and silver ornaments are precious".
The following notations are used:
$G(x): x$ is a gold ornament
$S(x): x$ is a silver ornament
$P(x): x$ is precious
(A) $\forall x(P(x) \implies (G(x) \wedge S(x)))$
(B) $\forall x((G(x) \wedge S(x)) \implies P(x))$
(C) $\exists x((G(x) \wedge S(x)) \implies P(x))$
(D) $\forall x((G(x) ∨ S(x)) \implies P(x))$
Basically statement is saying that for every thing, if it is a Gold ornament or a silver ornament, then it is precious.
So, $\forall x((G(x) ∨ S(x)) \implies P(x))$ is correct logical formula.
