Translate each of these statements into logical expressions using predicates, quantifiers, and logical connectives. a) Something
yKpoI14uk [10]

Answer:

Let P(x) = x is in the correct place

Let Q(x) =  x is in the excellent place

R(x) denotes the tool

Explanation:

a) Something is not in the correct place.

P(x) is that x is in the correct place so negation of ¬P(x) will represent x is not in the correct place. ∃x is an existential quantifier used to represent "for some" and depicts something in the given statement. This statement can be translated into logical expression as follows:

                                                    ∃x¬P(x)

b) All tools are in the correct place and are in excellent condition.

R(x) represents the tool, P(x) represents x is in correct place and Q(x) shows x is in excellent place. ∀ is used to show that "all" tools and ∧ is used here because tools are in correct place AND are in excellent condition so it depicts both P(x) and Q(x). This statement can be translated into logical expression as follows:

                                       ∀ x ( R(x) → (P(x) ∧ Q(x))

c) Everything is in the correct place and in excellent condition.

Here P(x) represents correct place and Q(x) represents excellent condition ∀ represent all and here everything. ∧  means that both the P(x) and Q(x) exist. This statement can be translated into logical expression as follows:

                                              ∀ x (P(x) ∧ Q(x)
