Hi,

I'm currently going through past exams papers as part of my revision for my upcoming exams, however the past papers that I am using do not include answers, so I'm not sure if I'm on the right track or not.

The question I'm working on is:

Which of the following columns (A) to (D) correctly completes the truth table for the expression?

The expression is 'p implies not q and r'. (I'm not sure how to type it mathematically).

p q r (A) (B) (C) (D)

F F F T T F T

F F T F T T T

F T F T T F T

F T T F T T T

T F F F F F F

T F T F T T F

T T F T F F T

T T T F F T F

I have tried to work it out and I've come out with column C. Can anybody tell me if that's correct, or where I might of gone wrong if it's not?
