I have a question where I was given the following atomic propositions:
Let H(x) = x can ski
Let P(x) = x plays soccer
Note: The universe of discourse is all humans
I was tasked to translate the following sentence logically:
No one who can ski plays soccer
I came up with two solutions for this sentence and I'm unsure if one is considered more correct:
∀x(¬(P(x)∧H(x))
∀x (H(x) -> ~p(x))

Your second sentence can be rescued by removing the negation at the beginning: $$\forall x (H(x)\to\neg P(x)).$$ This translates to, For every person, if they ski, they don't play soccer. This is equivalent in English to saying that nobody who skis plays soccer.
