Answer:
"There exists a good book that does not have a plot twist and does not have a surprise ending".
Step-by-step explanation:
We negate the universal quantifier "for all" or equivalently "In every" using the existential quantifier "There exists". So, we negate "In every good book" as "There exists a good book". In the other hand, we have the propositions
P: there is a plot twist
Q: there is a surprise ending,
and the conjunction
P ∨ Q. We negate this conjunction using the De Morgan's Laws as
¬(P∨Q) = ¬P∧¬Q
i.e., does not have a plot twist and does not have a surprise ending. Therefore, we negate "In every good book there is a plot twist or surprise ending" as "There exists a good book that does not have a plot twist and does not have a surprise ending".
There are infinitely many primes p such that p + 2 is also prime. This is through the Twin Prime Conjuncture, but has not been proven yet.

Answer:
2 bags
Step-by-step explanation:
