Question

Let F(x, y) be the statement "x can fool y," where the domain consists of all people in the world. Use quantifiers to express each of these statements.

Answer 1

$F(x,y)=(\text{x can fool y})$

$\text{domain of } x = \text{"all people in the world"}$

$\text{domain of } y = \text{"all people in the world"}$

$\forall{x}\exists{y}F(x,y)$

Answer: $\forall{x}\exists{y}F(x,y)$
