Prove whether each argument is valid or invalid. First find the form of the argument by defining predicates and expressing the hypotheses and the conclusion using the predicates. If the argument is valid, then use the rules of inference to prove that the form is valid. If the argument is invalid, give values for the predicates you defined for a small domain that demonstrate the argument is invalid.

The domain for each problem is the set of students in a class.

Exercise 7 . 73. 5: Determine and prove whether an argument in English is valid or invalid . @ About Prove whether each argument is valid or invalid . First find the form of the argument by defining predicates and expressing the hypotheses and the conclusion using the predicates . If the argument is valid , then use the rules of inference to prove that the form is* valid . If the argument is invalid , give values for the predicates you defined for a small domain that demonstrate the argument is invalid. The domain for each problem is the set of students in a class . ( a ) Every student on the honor roll received an A . No student who got a detention received an A. No student who got a detention is on the honor roll . ( 0 ) No student who got an A missed class No student who got a detention received an A. No student who got a detention missed class! ( C ) Every student who missed class got a detention . Penelope is a student in the class! Penelope got a detention Penelope missed class ( d) Every student who missed class got a detention . Penelope is a student in the class . Penelope did not miss class . Penelope did not get a detention . ( e ) Every student who missed class or got a detention did not get an A. Penelope is a student in the class . Penelope got an A.
