Challenge Problems
Push your limits with advanced challenges

💡 Hint: Focus on how you can relate the two groups in a logical expression.
Construct a proof showing that if a student is not a senior, they cannot graduate. Use predicates and quantifiers to represent your logic.
💡 Hint: Pay close attention to the contrapositive of the statement.
