 (From Discrete Mathematics by Kenneth Rosen)
Consider the following predicates. 

Consider the following predicates. F(p): Printer p is out of service. B(p): Printer p is busy. L(j): Print job j is lost. Q(j): Print job jis queued. Translate the following specifications into English. a) 3p (F(p) ^ B(p)) → 3jL(j) b) Vp B(p) → jQ() c) 3j (Q() AL()) → 3p F(p) d) (Vp B(p) ^ VjQ()) → ()

Expert Solution
Specifications

a. ∃p (F(p) / B(p)) → ∃j L(j)

 

b. ∀p B(p) → ∃j Q(j)

 

c. ∃j (Q(j) / L(j)) → ∃p F(p)

 

d. ∀p B(p) / ∀j Q(j) → ∃j L(j)
