Hi

I am trying to answer the question which I have attached. Please tell me if the answers are correct.

a) let M(x,y) = x has forgiven y R(x)= x is a saint

U=universe of discourse= all humans

b)let R(x) = x is in calculus class ; Q(x) = x is in discrete math class

M(x,y)= x is smarter than y

U=universe of discourse = all humans

c)let P(x) = x likes mary ; R(x) = x is mary

U=universe= all humans

d)let P(x) = x is a police officer

Q(x) = x is jane

R(x)= x is roger

M(x,y) = x saw y

U=universe= all humans

e)let P(x) = x is police officer

M(x,y) = x saw y

let j=jane and r=roger

again U=universe of discourse = all humans

thanks
