My English teacher has gave us this assignment in conjunction with mathematics, and points added based on how good we answer (EC in both classes). Apparently it's supposed to teach us how to properly back up our ideas in essays or proofs or something, but anyways, the assignment is as follows.
Scenario: A priest and a rabbi walk into a bar.
1) Who will exit the bar first? Back up your ideas with empirical evidence.
So far, this is what I have derived:
Corollary 1: The bar would have a bartender, seeing as someone needs to run the place. Therefore, the bartender's presence can affect the priest's and the rabbi's.
Corollary 2: Given that the priest and the rabbi walk into the bar, it can be derived that the priest and the rabbi are at one point in the bar together. If one left before the other entered, then it would be impossible to decide how to judge which one exited first, as no parameters are set (I'm a little shaky proving this one.)
Corollary 3: The day is not specified, so:
Scenario 3-1: The day is Saturday.
Scenario 3-2: The day is Sunday.
Scenario 3-3: The day is not Saturday or Sunday.
6 possible scenarios:
3-1-1: The rabbi is the first to leave, as he is observing the Sabbath.
3-1-2: Both priest and rabbi celebrate the Sabbath on the seventh day.
3-1-3: Neither leave.
3-2-1: The priest leaves early to celebrate the Sabbath on the first day.
3-2-2: Both priest and rabbi celebrate the Sabbath on the first day.
3-2-3: Neither leave.
So far, it is a 50-50 chance between the priest and the rabbi leaving the bar first. Thus,
Corollary 4: The determining factor will be something in the bar itself, and not a religious factor standing alone. This does not rule out the possibility of one of the two being offended by something they see.
And this is where I get stuck.
