Free ticket problem
"Free ticket problem is a simple question which was derived by me when I lost an opportunity to get a free airline ticket.". This is orginal research, which wikipedia cannot accept. See WP:NOR. Kappa 14:02, 27 Mar 2005 (UTC)
 * 1) Delete. This is just an example of probability. --EnSamulili 14:42, 27 Mar 2005 (UTC)
 * Delete. Not only is this original research, it is also wrong. The events 1, 2, etc. (as used in the calculations) are obviously not independent, so the calculations are irrelevant. (For example, if the first person gets the ticket, the second certainly doesn't.) The exact (and entirely non-noteworthy) solution is P(i)= 1/n for all i.

 * Keep. Dear Arbor, I got the answer and your advise, sorry so much, and thank you so much for your advise . And the answer is now correct!. We can treat this as a useful example of conditional probability, so that students like me are no longer make a mistake between the selectiom of independent and dependent events. So, keep this as it is now and add the link to it in the conditional probability page as "An example of conditional probability" 202.172.246.7 05:26, 29 Mar 2005 (UTC)


 * Delete. "Free ticket problem" is not where anyone would look to find an example of probability. Oh, and, it's wrong. If they all open their envelopes "together" as the article says, then the events are independent and the probability is 1/6. If they open them in the order received, then P(student n has ticket given than students 1 through n-1 did not) = 1/7-n)) . FreplySpang 16:05, 27 Mar 2005 (UTC)


 * Delete. As others have said, not only is it something the author made up, it's wrong (and obviously so to anyone who knows anything about probability; it has the probabilities of the different outcomes adding up to more than one, for crying out loud). Josh Cherry 01:53, 28 Mar 2005 (UTC)
 * Delete. Bad original research. Jayjg (talk) 05:13, 28 Mar 2005 (UTC)
 * While the question it asks is mildly interesting, this article needs to be under a different name (because there is no reason for it to be known by that name) and with different content (because it's wrong). So I guess that's a delete then. DJ Clayworth 22:12, 28 Mar 2005 (UTC)
 * Keep this is a better article than one on a pokemon character. --Spinboy 23:47, 31 Mar 2005 (UTC)
 * Delete spurious article. PatGallacher 23:53, 2005 Mar 31 (UTC)
