Question

if i could be in two places at the same time, I'd come to your party. (b). I did not come to your party. (c). therefore i cannot be in two places at the same time. Give the symbolic notation for the arguement

Answer 1

That looks like a contrapositive. Was there anything before the word if?

Answer 2

nope
the only clue he(lecturer) gave was modus tollens

Answer 3

modus tollens is also known as the law of contrapositives.

If you have p->q (p implies q) and you have not q

Then not p follows

Answer 4

Here, q = I'd come to your party
~q (not q) = I did not come to your party

Answer 5

owkay

Answer 6

so the whole equation becomes [(p->q)^¬q]¬p, right?

Answer 7

I think so.

Answer 8

thanks
