In the quiz of Mutually Exclusive Sets lesson Even numbers and prime numbers were considered complements, why?

Hey M.S.M, The answer "prime numbers and even numbers" isn't incorrect because they're compliments, but because they aren't mutually exclusive. As Jacobo has noted, the number 2 is simultaneously even and prime, which makes this answer incorrect. The correct one is ending in a draw or winning a game, since you can't do both at the same time, but you can also lose a game, which means they aren't complements. Best, 365 Vik
