Question

Let P (x) denote the statement “x >7.” Which of these have truth value true?

(a) P (0)

(b) P (4)

(c) P (6)

(d) P (9)

This question was addressed to me during an online interview.

I would like to ask this question from Predicate Logic Quantifiers in section The Foundation: Logics and Proofs of Discrete Mathematics

Answer 1

Correct answer is (d) P (9)

For explanation I would say: Put x=9, 9>7 which is true.
