    Discrete math

    I have some questions here that I'm a little unsure of....I'm not sure of what approach to take. The question is
    "Let P(x) and Q(x) be predicates and suppose D = {1, 2, 3} is the domain of x. Do the following statement forms have the same truth value?

    1: For all x in D, ( P(x) v Q(x) )
    2: (For all x in D, P(x) ) v (For all x in D, Q(x) )

    I have an idea but does anyone know the correct approach to this?

    Re: Discrete math

    What answer did you get, yes or no?
    If yes, explain why. If no, give a counter example
