The 3-ball lottery |
2009-12-09 |
|
Lee pose la question :
A friend and I are trying to calculate the odds of choosing the winning
numbers in the 3-ball lottery (3-digits 0-9).
We realize that there are 720 Permutations and 120 possible Combinations
of said lottery, but we're having trouble figuring how to determine the
"odds" or probability of winning (1) when order matters, and (2) when it
doesn't. Please help!
