Question
I've been trying to figure this out for 2 days. hope you can help
Question: Ms. Jackson announces that a test will be given on one of the five week days of next week, but tells your class, “You will not know which day the test is until you are informed at 8a.m. of your 1p.m. test that day.” Why isn’t the test going to be given?
This is a well-known and well-discussed problem. I have also analysed this problem quite deeply and posted my viewpoint at http://agarwal-rohit.blogspot.com/2007/02/surprise-that-never-was.html .
However, I have recently started having doubts about my discussion. However, this might help you appreciate the problem.
btw, you can always google for others' viewpoint.
hope it helps,
Rohit
