Now imagine there are 100 doors instead of 3. One of them has a car 99 have a goat.
You pick one at random. Moderator opens the remaining 98 doors with goats. Do you switch to the only closed door? Still think it's 50%?

sorry for wording it badly, i'm mainly wondering how do i represent rules of inference with pure propositional logic (using equivalence rules)

so if for some reason i wasnt allowed to use a rule of inference like hypothetical syllogism, how do i do it with equivalences only?

also how do people do direct proofs, are these the hardest to do? i found i can only solve most problems by doing a contradiction proof because it gives me more things to work with

and can ANY argument be solved with a direct proof, or do some have to be solved by contrapositive or contradiction?

thanks anons

Why can't a learn anything apart from maths?
I went back to university to study computer hardware but I struggle and just memorise it all instead of learning and understanding.

Can we prove free will by simply writing the series of prime numbers or other sequence on a sheet of paper?

It begs a more interesting question:
Where will you be when the cat reveals himself?

So, you all know some form of thought experiment of copying your body. If you destroy the original, do you think your mind remains the same, "you", between bodies? If not, why?

Personally I don't see how it wouldn't be the same. Everything you experience and remember gets copied as-is, and there will be no apparent difference to you. So what factor would make the copy not be you?

Let's say the owner has $500 at the start

Scenario 1:
>loses $100 from robbery
owner now has $400
>lady comes back and pays $70
owner now has 470

Scenario 2:
>Lady pays 70$
owner now has $570

There's a $100 difference, which means he lost $100
