Question

Complete the truth table for p or q. Place an "x" in the box for a true statement.

P Q P or Q
t t ?
t f ?
f t ?
f t ?

Answer 1

I dont know what the P or Q means.

Answer 2

P and Q are just unknown logical statements (like x is an unknown number)

Answer 3

So if P is true and Q is true, then is "P or Q" true?

Answer 4

yes...

Answer 5

So wouldn't they all be true then because in every one atleast one is true?

Answer 6

You are correct, in every line, either P or Q (or both) is true

Answer 7

except the last one.

Answer 8

hmm is there a typo in the last line?

Answer 9

Yes :) My fault.

Answer 10

So the table fills out to be

P Q P or Q
t t t
t f t
f t t
f f f

I'm assuming that the second 't' in the last row should be an 'f'

Answer 11

oh in this odd case, they want you to use 'x's instead of 't's...but you get the idea

Answer 12

yes. :) thank you for clarifying!

Answer 13

you're welcome
