p = T, q = F, and r = F.

Select the expression that evaluates to true.

A): p∨r
B): q∨r
C): ¬p
D): p∧q
 
 

2):  The propositional variables f, h, and p represent the propositions:

 

f: The student got an A on the final.

h: The student turned in all the homework.

p: The student is on academic probation

 

Select the logical expression that represents the statement: “The student is not on academic probation and either the student got an A on the final or turned in all the homework.”


A):  ¬p∧(f∨h)
B):   (¬p∧f)∨h
C);   ¬p∧f∧h
D):   ¬(p∧f)∨h
