Statistics Question for 600 Ticket Raffle Draws?

[TheGrayRider]

Probably 35 years since I took undergraduate statistics course. Question(s) for younger & brighter minds:

How do you calculate the true odds if you buy several raffle tickets of a limited 600 ticket big game raffle?

If I buy the first ticket, I think the odds are 1/600. Then the second ticket, the odds are 1/599. Do you add or multiply or divide the first and second fractions to determine your true odds thereafter?

I am getting old. Thanks in advance, TheGrayRider.

Divide your number of tickets by the number available. If you buy 10 tickets your odds are 10/600= 1.66%.

Funny, I got on here to talk about raffle odds....

Yep, if there is only one "prize" your odds just scale linearly with the number of tickets you buy.

If there is more than one winning ticket the calculation changes.

Or if they don't sell all the tickets.

What raffle did you purchase a ticket for? If you bought one ticket with only 100 sold simple math would say that’s 1 percent so if you bought 1 out of 600 tags then that would be .60 of a percent

I am certainly no mathlete myself, but I believe that example would be 1/6th of a percent (.167%), not 6/10th of a percent (.6%).

The 1:600 are a lot better than the AZ Desert sheep tag I drew. That was 1:122 that nobody took my tag in the bonus round then 1:34,000, and multiply that with the “up to 10%” non resident penalty…or the Utah NR mountain goat tag I drew which was 1:2412. Same year I drew goat I drew Alaska fall Musk Ox…and the one day I was home between the Ox and goat hunt, Oak called to tell me I won my choice of Swarovski in the RMBS raffle which turned into a 95mm BTX. I believe I bought 3 tickets that year.

If you buy into a raffle thinking you have great odds to win you are going to be very disappointed. Much easier on the psyche knowing you are helping the cause and have done a good deed. Every so often you will be blessed

And to try to pay back those wins, I am now a life member of the RMBS, the ADBSS, and the Alaska Bowhunters Association.

Start a hunt fund. Every time you buy a raffle ticket or membership (annual or life) deposit the same amount into the hunt kitty. Throw $100 a month in it too. We all can shave off $25/week somewhere. It all adds up.

I believe 1 chance in 600 would be 1/6 of 1%, which is not quite the same as 0.6%

It’s just simply 1 divided by 600. Multiply by 100 for percentage. 0.166% which is 1/6 of 1%
