Practice question · Select all that apply
Let p be TRUE and q be TRUE. Select every statement that is FALSE.
Hints
- You are hunting for the false ones, evaluate each, do not guess.
- Any statement that requires p to fail is doomed here, since p is true.
Show the answer
- B. (NOT p) AND q
- D. NOT (p OR q)
- E. NOT p
Why
With both true: p AND q is true; NOT p is false; p OR (NOT q) is true because p holds; (NOT p) AND q is false because NOT p fails; NOT (p OR q) is NOT true = false. So the false ones are options 2, 4 and 5.
