tic-tac-toe (Posted on 2004-07-30) Difficulty: 3 of 5
If I put nine pieces of paper, with a digit from 1-9 written on each one, into a hat, and pull 3 out without replacement, what is the likelihood that I will select three numbers that result in a winning tic-tac-toe?
 1 | 2 | 3

 4 | 5 | 6

 7 | 8 | 9
