True or False 1. To disprove ∃xP(x), provide an example for which P(x) is false for at least one x. 2. Let F(x,y): x can fool y where D = set of all Filipinos. Then, "Marc cannot fool everybody." is the same as ∀y(~F(Marc,y)). 3. (p⇒q) implies p⇒(q∨r) by Addition. 4. (p⇒q) implies p⇒(q∨r) by Addition.

3. Argue that the following implication is true [(\x)P(x) ✓ (\x)Q(x)] ⇒ (Vx) [P(x) ✓ Q(x)] Is this statement biconditional (i.e is the converse implication true)? How about if we replace V with ^? 1
