AI Thread Summary
The discussion centers on a request for help with statistical questions related to a tic-tac-toe board. The initial response emphasizes that the participants will not complete the homework for the requester. A calculation is provided, indicating that there are 504 possible configurations for placing three "X"s on the board. The conversation then poses specific questions about the configurations of "X"s in vertical columns, horizontal rows, and diagonals. The focus remains on understanding the statistical arrangements within the game.

(29) A "tic-tac-toe board" has 9 positions. There are 9 places to put the first "X", then 8 places to put the next, and then 7 places to put the last: there are total of 9(8)(7)= 504 possible configurations for 3 "X"s on the board. How many of those have all three "X"s in the same vertical column? How many have all three in the same horizontal row? How many diagonal are there?
 

Thread 'Deductive proof in logic formal systems'

I was reading documentation about the soundness and completeness of logic formal systems. Consider the following $$\vdash_S \phi$$ where ##S## is the proof-system making part the formal system and ##\phi## is a wff (well formed formula) of the formal language. Note the blank on left of the turnstile symbol ##\vdash_S##, as far as I can tell it actually represents the empty set. So what does it mean ? I guess it actually means ##\phi## is a theorem of the formal system, i.e. there is a...
