[edit] Oyam's Pyramid

The article Oyam's Pyramid is currently proposed for deletion. It seems to me that it would be likely to be covered by some area of mathematics rather than being a complete hoax, but I've been unable to track down any evidence for its existence with this title. Could somebody take a look and see if a) it's a valid but wrongly-titled article, b)it needs merging or redirecting to some other concept, or c) it's complete garbage.

You should take this request to Wikipedia talk:WikiProject Mathematics. -- Meni Rosenfeld (talk) 16:42, 31 July 2006 (UTC)
Thanks, I've copied it over there now. Yomangani 16:51, 31 July 2006 (UTC)

[edit] math

what is half of 3/4 (image removed)

You should use parentheses to make the expression unambiguous. The result can be either \frac{3}{8[[Image:Example.jpg]]} or \frac{3[[Image:Example.jpg]]}{8}. -- Meni Rosenfeld (talk) 16:46, 31 July 2006 (UTC)
That's silly. —Keenan Pepper 21:56, 31 July 2006 (UTC)
What's silly about it? Image:Example.jpg is just a chunk of binary data, and can therefore be read as a (594416 bit) number, if you want to. While I havn't worked out that number, not least because I have better things to do (not that you'd think so given that I've bothered to post this...) I can confidently say that the value of the first expression is very close to zero, and the second is stupidly large. -- AJR | Talk 13:08, 2 August 2006 (UTC)

[edit] dice problem

how many times must 2 dice be trhown to ensure that the same total score occurs at least 6 times? and how many times must n dice be thrown so that the same total score occurs at least p times?

Well, try figuring out how many possible totals the n dice might return in a throw. In the worst case, you'll begin a session by throwing each of these totals p - 1 times. So figure out how long that takes, then add one! Melchoir 23:42, 31 July 2006 (UTC)
This is a stupid question. ((Homework answer removed.)) Ohanian 00:48, 1 August 2006 (UTC)
