Question

If P is T, Q is F, and R is T, find the truth value of {(R => - Q) v (P^ -R)} => Q

Answer 1

What's the (P^ -R) mean?

Answer 2

Is that supposed to be an AND?

Answer 3

Yes

Answer 4

Just to be sure then, in english, the statement is
[({R implies NOT Q} OR {P AND NOT R}) implies Q]

Answer 5

Correct

Answer 6

nevermind, I made a mistake. It should actually be FALSE.

Answer 7

If P=T, Q=F, R=T, then (R => ~Q)=T. Thus, {(R => ~Q) v (P ^ ~R)}=T.This means the statement is saying (T => F) which is false. So the statement is FALSE.

Answer 8

Thank you.

Answer 9
