How to calculate odds
My state posts odds online for new scratch-off games. But once the game has been sold for a while, I assume the odds have changed. Is that correct? So, for example, if there were 10 of the top prize available at the beginning, but 6 have been won, how do you calculate the odds for the remaining 4 top prizes? More important, how do you calculate the odds for all remaining prizes as a group? Thanks.

That's the odds I get when I calculate odds for matching 5/5 with 75 balls. However, MM has it at 18.5 mil. Do you know how they calculate their odds for 5/5? Just curious.

How can I calculate odds?
If I'm playing the Cash 25 and I'm playing a wheel where I choose 10 numbers (instead of 6), how much does that increase my odds of winning? The WV lottery site says that the odds of matching 6 are 1:177,100. But what if I choose 10 numbers and only have to match 6?

The draws are independent of each other. If one state has one draw a day for 50 days, there is always the chance that the same number sets will come up. (this has happened), Or one state has 50 draws in one day, or 50 states has one draw in one day, it's all the same. The odds are 1/1000 for each ticket.Quote: Originally posted by Todd on December 31, 2003TC,When trying to calculate odds for a specific pick across all states, how would you do it?

TC,When trying to calculate odds for a specific pick across all states, how would you do it? I know one straight pick in a state is 1/1000, but if there are 48 drawings, I don't think it becomes 48/1000, because there is the possibility that different states can have the same numbers come up. How would you calculate the odds?

Hey George,I'll bet with your knowledge and ability to calculate odds, you'd make a great craps player! I totally love playing craps, but one of my favorite ways -- betting against the roller -- requires the ability to quickly calculate odds and lay the correct bet.

Are pre-draws corrupting your lottery strategy ?Reply
You really gotta share a link with everyone here so we can all learn your awesome mathematics, really man, this is great stuff!! Am i denying a never drawn list? I just posted one, perhaps you missed it again, just like all those other facts i have posted. You are mixing up some things here. Ofcourse a number can go past 1000 draws before showing up, i showed that in that little list i posted half an hour ago which has info on all the states. And i know, it is a little list, one might have

How are odds calculated?Reply
That's how I know to calculate odds (math is not my strong suite). However, on the MM playslip, the odds of 5+0 are 3,904,701. I have wondered where they come up with that number, instead of 3,819,816.

If I reduce the MM or PB number pool by half and play 3o2e/3e2o...(?)Reply
Also, I didn't catch thiis the first time. Go back and look at how you started this thread. You asked a question about probability that had a simple answer that you didn't know and couldn't figure out on your own.Simple probability allows us to very easily and precisely calculate the odds, but you asked what we thought the odds would be. Somebody who can't do such basic calculations on probability is not pretty versed in probability, regardless of what they may have known or studied in th
