Title: unexpected exam pardox
Post by gkedem on Feb 12^th, 2006, 10:28am

I have yet to be given a convincing resulotion for this paradox.
a teacher anounces to his pupels thet in the coming week ther will be a pop quiz, the puples began to think when the pop quiz might take place. they concluded thet the quiz can't take place on friday since friday is the last day of the week so after tuesday they will be sure thet the quiz will take place on friday and it wuldn't be a suprise. so they decided the quiz can't take placw on tuesday ether since it can't after thursday they will be sure it must be on tuesday (it can't be on friday) and it wuldn't be a suprise, and so on for all the days of the week.

lets presume thet the teacher conduct tests at 8 oclock in the morning only.

a pop quiz is such thet you can't tell with absolute certenty when will it take place up to the moment it starts.

There is already a long thread (http://www.ocf.berkeley.edu/~wwu/cgi-bin/yabb/YaBB.cgi?board=riddles_hard;action=display;num=1028031934) for this riddle. (With many correctly spelled words in it! :o)
