Are these statements true or false? The universe of discourse is the set of all people and P(x,y) means \'\'x is a parent of y\'\' (a) (b) (c) (d) (e) Solution ?x?yP(x,y) would mean \"there exists x ( for which ) there exists y such that x is a parent of y\". Now the negation at the beginning I would think is applicable to the first quantifier. So we may as well bracket it (.
