Answer
True. The formal statement is: $\forall$ characters u, if u occurs in the sequence Discrete Mathematics, then u is lowercase.
The negation is: $\exists$ at least one character u such that u occurs in Discrete Mathematics and u is not lowercase.
The negation is false because Discrete Mathematics does not contain a character u. So the claim is vacuously true (or true by default).
Work Step by Step
A statement of the form $\forall x \in D$, if P(x) then Q(x) is called vacuously true or true by default if, and only if, P(x) is false for every x in D.
