I have been working on logical expressions for a bit, I am still very much a beginner, I stumbled upon this question today and attempted to solve it, unfortunately, I am not too sure whats going on.
Any help is greatly appreciated .
The question
P(x) be the predicate "x is a Knight"
Q(x) be the predicate "x is a Wizard"
R(x) be the predicate "x likes archery"
The universe of discourse is all people
a. ∃ (() ∧ ¬() ∧ ())
b. ∀ (() ∧ ¬() ∧ ())
c. ∀ (() → ())
What i have so far
A) At least on of the people is a knight and not a wizard and likes archery
B) Living amongst people is a knight and not a wizard and likes archery
C) If living amongst all people is a knight then they like archery
Thanks
