GUEST,Jim Dixon BS: Mathematical Probability Query (103* d) RE: BS: Mathematical Probability Query 11 Oct 00

I agree with Marion's answer. Here's a variant of the puzzle which might make it more clear:

Instead of 3 cups, suppose there are 1,000 cups. You choose number 483 at random. Then the house turns over all the cups EXCEPT numbers 483 and 722, showing that all 998 cups are empty. Now, would you keep number 483? Or switch to number 722?
