Answer to Question #259364 in Discrete Mathematics for hamza

Question

all swedish movies are serious

Answer 1

Let the domain be the domain of Swedish movies, and let $M(x)$ be the predicate “$x$ is serious.”

Then the statement can be written $∀xM(x),$ and the negation is $¬∀xM(x) ≡ ∃x¬M(x),$

or, in English, some Swedish movie is not serious.
