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

The required probability that the individual will select three numbers that result in a winning tic-tac-toe is approximately 0.095238
