4 number combinations |
2009-09-10 |

From jeremy:
Here's my question...
I've been playing the lottery, I know what a waste of time. I would like to know how many 4 number combinations can be derived from a set of 10 numbers, when no number can be repeated in the present string of 4 numbers being selected.
