Give a useful denial of each statement.
a) T is not bounded or T is compact. (Assume that T is a fixed objet.)
b) Ali is studying Mathematics and English.
c) If Ahmad was here, he can answer your question.
My attempt:
a) T is bounded “and” T is not compact.
b) Ali is not studying math “or” English.
for (c) I know that, $\lnot (P \implies Q)$ is $P \land \lnot Q$, so I think the answer is:
c) Ahmed was here “and” he can not answer your question.
Is that true? Thanks.
