Let S(x) be the predicate "x is a student" F(x) be "x is a faculty member" And A(x,y) the predicate "x has asked y a question" where the domain consists of all people associated with your school. Use quantifier to express each of these statements.

e) There is a faculty member who has never been asked a question by a student.

I want to ask few questions:-

As "a" is denoted by "there exists" So why "for all" is used in kenneth rosen answer, when it is clearly said that never been asked a question by a student not any student.
