assuming you need to pick six numbers from 1 to 49, that gives 49 possibilities per "slot."
that means there are 49^6 possible combinations. that's 13841287201 ways of picking six numbers, 1-49.
if i'm not mistaken (been a long time since i took statistics too) the probability you pick the right numbers in the right order is 1/13,841,287,201

You are a little off in your logic here. There are only 49^6 possible numbers if you could pick the same number all 6 times (ex. a draw of 12 12 12 12 12 12), which can't happen. You can only pick each number once, without replacement. This means that you could have 49 * 48 * 47 * 46 *45 *44 = 10,068,347,520 different draws.
Ahhh, but we are not finished yet. We have to take in account of the fact that we could get the same numbers in different orders. (Are we having fun yet!!!??) For example, (1 2 3 4 5 6) is the same as (6 5 4 3 2 1). So we must find out how many ways are possible. This is 6 *5 *4 *3 *2, or 6! = 720.
Now take the 10,068,347,520 and divide it by 720. You get 13,983,816. So your chances of winning are 1 in 13,983,816, or roughly .0000000715112.
I should get back to work, but I'll try to post the other odds (getting 4 or 5) later. Or you could just follow the logic and do it yourself!
