[ QUOTE ] [ QUOTE ] Here is a cooler problem, imo: show that the expected value of the # of people who get their hat back is 1, independent of n. [/ QUOTE ] How is this cooler? This is way easier to solve than the original problem, just use <font color="white"> indicator functions </font> <---- answer in white. [/ QUOTE ] Cooler in that it admits several elegant and simple solutions. To me, easier problems are cooler. [/ QUOTE ] Can't disagree with that =). That post also jarred my memory and reminded me of an amazingly simple solution to the 1st problem using exponential generating functions. Thanks [img]/images/graemlins/smile.gif[/img] |
